1.9 Fundamental Operations What are the Fundamental Operations?

Addition, Subtraction, Multiplication and Division We will be applying these fundamental operations to rational expressions. Uhoh. What is a rational expression? Yes it is. This will all be review. We are working on the little things here.

Simplify the following Hint: Often it will be easiest to factor first before you continue with the operation. THAT’S why we did factoring last chapter!! What is the domain of problem 1? 4. What is the domain of problem 3?

What do you do if the problem doesn’t factor nicely?

By the way… if you know synthetic division, you can’t use it. Did I trick you?
