Book description:

In this book, you will learn how to manipulate a rational expression by multiplying it by a disguised form of 1. You will use this skill to do the following operations with rational expressions: addition, subtraction, multiplication and division. You will then learn how to solve rational equations by identifying common denominators and eliminating the fractions. Near the end of the book, you will learn that some equations have extraneous solutions. This book builds on Algebra 1: Book 5 and Algebra 2: Book 3.
