We started the topic of rational expression operation today. A rational expression is a fraction with either numerator or denominator or both being a polynomial. As such, all rules for dealing with factions apply.

A rational expression is simplified if there is no common factor between the numerator and denominator (other than 1 or -1).

We covered rational expression multiplication and division, followed by addition and substraction. The goal is to reach a rational expression in its simplified form after the operation.
