### Algebra 1: Standard 12.0: Simplifying Rational Expressions

By

Ben Oyler,

Jerred Montgomery,

and Anthony Morgan

What Is This?

A rational expression is an algebraic expression whose numerator and denominator are polynomials. The value of the polynomial expression in the denominator cannot be zero since division by zero is undefined. This means that rational expressions, like rational functions may have excluded values.
