Ok welcome to this last lesson in the chapter the topic is simplifying rational expressions. Knowing how to simplify a rational expression is really important in algebra so you want to focus on the skills I’m going to teach. A rational expression is basically a fraction with variables. So simplifying a rational expression can be thought of as “reducing” a fraction with variables.
Things to focus on this lesson:
• what a rational expression is
• factoring
• how to cancel like factors
