Section 8.8

In this lesson you will learn to add, subtract, multiply, and divide rational expressions. In the previous lesson you combined a rational expression with a single constant or variable by finding a common denominator. That process was much like adding a fraction to a whole number. Likewise, all of the other arithmetic operations you will do with rational expressions have their counterparts in working with fractions. Keeping the operations with fractions in mind will help you understand the procedures.
