Intro

A rational expression is a fraction that its numerator and/or <a href='[[glossary.html|{"keyword":"Denominator","term":"Denominator"}]]'>denominator</a> are polynomials. In this lesson, we will first learn how to find the non-permissible values of the variable in a rational expression. Then, we will how to simplify rational expressions.
