5. Rational Expressions: Reduce, Multiply, Divide, Add and Subtract

Introduction to Module 5

In this module, we will introduce an algebraic form known as the rational expression which is precisely a ratio of polynomials. We will first learn how to reduce these expressions and then multiply, divide, add and subtract.

Module-level Objectives

As a result of the instruction in this module, students will be able to:

Identify algebraic forms which are rational expressions (CO=2)
Multiply rational expressions (CO=2
Divide rational expressions (CO=2)
Find the Least Common Denominator (LCD) for a set of denominators (CO=2)
Add and subtract rational expressions (CO=2)
(CO = Course Objective. This demonstrates the alignment from the module objective to the course objective[s].)
