Preface
It is with pleasure that we offer the fifth edition of Beginning and Intermediate Algebra.
With each new edition, the text has been shaped and adapted to meet the changing
needs of both students and educators, and this edition faithfully continues that
process. As always, we have taken special care to respond to the specific suggestions
of users and reviewers through enhanced discussions, new and updated examples and
exercises, helpful features, updated figures and graphs, and an extensive package of
supplements and study aids. We believe the result is an easy-to-use, comprehensive
text that is the best edition yet.
Students who have never studied algebra—as well as those who require further review of basic algebraic concepts before taking additional courses in mathematics,
business, science, nursing, or other fields—will benefit from the text’s studentoriented approach. Of particular interest to students and instructors will be the
NEW Study Skills activities and Now Try Exercises.
This text is part of a series that also includes the following books:
N Beginning Algebra, Eleventh Edition, by Lial, Hornsby, and McGinnis
N Intermediate Algebra, Eleventh Edition, by Lial, Hornsby, and McGinnis
N Algebra for College Students, Seventh Edition, by Lial, Hornsby, and McGinnis
NEW IN THIS EDITION
We are pleased to offer the following new student-oriented features and study aids:
Lial Video Library This collection of video resources helps students navigate the
road to success. It is available in MyMathLab and on Video Resources on DVD.
MyWorkBook This helpful guide provides extra practice exercises for every chapter of the text and includes the following resources for every section:
N Key vocabulary terms and vocabulary practice problems
N Guided Examples with step-by-step solutions and similar Practice Exercises,
keyed to the text by Learning Objective
N References to textbook Examples and Section Lecture Videos for additional help
N Additional Exercises with ample space for students to show their work, keyed to
the text by Learning Objective
Study Skills Poor study skills are a major reason why students do not succeed in
mathematics. In these short activities, we provide helpful information, tips, and
strategies on a variety of essential study skills, including Reading Your Math Textbook, Tackling Your Homework, Taking Math Tests, and Managing Your Time. While
most of the activities are concentrated in the early chapters of the text, each has been
designed independently to allow flexible use with individuals or small groups of students, or as a source of material for in-class discussions. (See pages 48 and 223.)

Preface
Now Try Exercises To actively engage students in the learning process, we now
include a parallel margin exercise juxtaposed with each numbered example. These allnew exercises enable students to immediately apply and reinforce the concepts and
skills presented in the corresponding examples. Answers are conveniently located on
the same page so students can quickly check their results. (See pages 3 and 87.)
Revised Exposition As each section of the text was being revised, we paid special
attention to the exposition, which has been tightened and polished. (See Section 1.4
Real Numbers and the Number Line, for example.) We believe this has improved discussions and presentations of topics.
Specific Content Changes These include the following:
N We gave the exercise sets special attention. There are over 1000 new and updated
exercises, including problems that check conceptual understanding, focus on
skill development, and provide review. We also worked to improve the even-odd
pairing of exercises.
N Real-world data in over 150 applications in the examples and exercises have been
updated.
N There is an increased emphasis on the difference between expressions and equa-
tions, including a new Caution at the beginning of Section 2.1. Throughout the
text, we have reformatted many example solutions to use a “drop down” layout in
order to further emphasize for students the difference between simplifying
expressions and solving equations.
N We increased the emphasis on checking solutions and answers, as indicated by
the new CHECK tag and ✓ in the exposition and examples.
N The presentation on solving linear equations in Sections 2.1–2.3 now includes
five new examples and corresponding exercises.
N Section 2.6 includes entirely new discussion and examples on percent, percent
equations, and percent applications, plus corresponding exercises.
N Section 3.4 on writing and graphing equations of lines provides increased devel-
opment and coverage of the slope-intercept form, including two new examples.
N Section 6.5 includes new coverage of simplifying rational expressions with nega-
tive exponents.
N Section 7.3 Introduction to Functions from the previous edition has been ex-
panded and split into two sections.
N Presentations of the following topics have also been enhanced and expanded:
Dividing real numbers involving zero (Section 1.6)
Solving applications involving consecutive integers and finding angle measures
(Section 2.4)
Solving formulas for specified variables (Sections 2.5 and 6.7)
Using interval notation (Section 2.8)
Graphing linear equations in two variables (Section 3.2)
Dividing polynomials (Section 4.7)
Factoring trinomials (Section 5.2)
Solving quadratic equations by factoring (Sections 5.6 and 11.1)
Solving systems of linear equations with decimal coefficients (Section 8.2)
Preface
xv
Solving systems of linear equations in three variables (Section 8.4)
Graphing linear inequalities in two variables (Section 9.3)
Solving quadratic equations by substitution (Section 11.4)
Evaluating expressions involving the greatest integer (Section 13.1)
Graphing hyperbolas (Section 13.3)
Evaluating factorials and binomial coefficients (Section 14.4)
HALLMARK FEATURES
We have included the following helpful features, each of which is designed to increase ease-of-use by students and/or instructors.
Annotated Instructor’s Edition For convenient reference, we include answers to
the exercises “on page” in the Annotated Instructor’s Edition, using an enhanced,
easy-to-read format. In addition, we have added approximately 30 new Teaching Tips
and over 40 new and updated Classroom Examples.
Relevant Chapter Openers In the new and updated chapter openers, we feature
real-world applications of mathematics that are relevant to students and tied to specific material within the chapters. Examples of topics include Americans’ personal
savings rate, the Olympics, and student credit card debt. Each opener also includes a
section outline. (See pages 1, 85, and 175.)
Helpful Learning Objectives We begin each section with clearly stated, numbered
objectives, and the included material is directly keyed to these objectives so that students
and instructors know exactly what is covered in each section. (See pages 2 and 130.)
Popular Cautions and Notes One of the most popular features of previous
CAUTION and NOTE to warn students
editions, we include information marked
about common errors and emphasize important ideas throughout the exposition. The
updated text design makes them easy to spot. (See pages 2 and 56.)
Comprehensive Examples The new edition of this text features a multitude of
step-by-step, worked-out examples that include pedagogical color, helpful side comments, and special pointers. We give increased attention to checking example
solutions—more checks, designated using a special CHECK tag, are included than in
past editions. (See pages 87 and 333.)
More Pointers Well received by both students and instructors in the previous edition, we incorporate more pointers in examples and discussions throughout this
edition of the text. They provide students with important on-the-spot reminders and
warnings about common pitfalls. (See pages 192 and 281.)
Updated Figures, Photos, and Hand-Drawn Graphs Today’s students are
more visually oriented than ever. As a result, we have made a concerted effort to include appealing mathematical figures, diagrams, tables, and graphs, including a
“hand-drawn” style of graphs, whenever possible. (See pages 188 and 261.) Many of
the graphs also use a style similar to that seen by students in today’s print and electronic media. We have incorporated new photos to accompany applications in examples and exercises. (See pages 109 and 176.)
xvi
Preface
Relevant Real-Life Applications We include many new or updated applications
from fields such as business, pop culture, sports, technology, and the life sciences
that show the relevance of algebra to daily life. (See pages 116 and 541.)
Emphasis on Problem-Solving We introduce our six-step problem-solving
method in Chapter 2 and integrate it throughout the text. The six steps, Read, Assign
a Variable, Write an Equation, Solve, State the Answer, and Check, are emphasized
in boldface type and repeated in examples and exercises to reinforce the problemsolving process for students. (See pages 108 and 337.) We also provide students with
PROBLEM-SOLVING HINT boxes that feature helpful problem-solving tips and
strategies. (See pages 139 and 338.)
Connections We include these to give students another avenue for making connections to the real world, graphing technology, or other mathematical concepts, as well
as to provide historical background and thought-provoking questions for writing,
class discussion, or group work. (See pages 195 and 251.)
Ample and Varied Exercise Sets One of the most commonly mentioned strengths
of this text is its exercise sets. We include a wealth of exercises to provide students
with opportunities to practice, apply, connect, review, and extend the algebraic concepts and skills they are learning. We also incorporate numerous illustrations, tables,
graphs, and photos to help students visualize the problems they are solving. Problem
types include writing , graphing calculator , multiple-choice, true/false, matching,
and fill-in-the-blank problems, as well as the following:
N Concept Check exercises facilitate students’ mathematical thinking and concep-
tual understanding. (See pages 96 and 196.)
N WHAT WENT WRONG? exercises ask students to identify typical errors in solu-
tions and work the problems correctly. (See pages 208 and 335.)
N Brain Busters exercises challenge students to go beyond the section examples.
(See pages 119 and 246.)
N
RELATING CONCEPTS exercises help students tie together topics and develop
problem-solving skills as they compare and contrast ideas, identify and describe
patterns, and extend concepts to new situations. These exercises make great collaborative activities for pairs or small groups of students. (See pages 209 and 264.)
N
TECHNOLOGY INSIGHTS exercises provide an opportunity for students to
interpret typical results seen on graphing calculator screens. Actual screens from
the TI-83/84 Plus graphing calculator are featured. (See pages 210 and 336.)
N
PREVIEW EXERCISES allow students to review previously-studied concepts
and preview skills needed for the upcoming section. These make good oral warm-up
exercises to open class discussions. (See pages 92 and 199.)
Special Summary Exercises We include a set of these popular in-chapter exercises in selected chapters. They provide students with the all-important mixed review
problems they need to master topics and often include summaries of solution methods and/or additional examples. (See pages 247 and 404.)
Extensive Review Opportunities We conclude each chapter with the following
review components:
N A Chapter Summary that features a helpful list of Key Terms, organized by
section, New Symbols, Test Your Word Power vocabulary quiz (with answers
Preface

immediately following), and a Quick Review of each section’s contents, complete with additional examples (See pages 224–226.)
N A comprehensive set of Chapter Review Exercises, keyed to individual sections
for easy student reference, as well as a set of Mixed Review Exercises that helps
students further synthesize concepts (See pages 227–228.)
N A Chapter Test that students can take under test conditions to see how well they
have mastered the chapter material (See page 229.)
N A set of Cumulative Review Exercises (beginning in Chapter 2) that covers ma-
terial going back to Chapter 1 (See page 230.)
Glossary For easy reference at the back of the book, we include a comprehensive
glossary featuring key terms and definitions from throughout the text. (See pages
G-1 to G-8.)
