Lesson Excerpt:

I. Introduction

- "Recently, we have been learning about multiplying rational expressions. We have been factoring rational expressions, cross reducing rational expressions and then multiplying them. Today, we are going to begin dividing rational expressions."
- "Let's just take a few minutes and review some of the things that we already know about division, and specifically about dividing rational numbers, and then we can take this information and apply it to dividing rational expressions."
- "A rational number is any number that can be written in fraction form or a/b form where the denominator can never be 0. Let's look at an example of dividing rational numbers."
