Simplifying rational expressions is a similar process to finding the lowest term of a fraction, as rational expressions are nothing more than fractions in which the numerator and the denominator are polynomials. To simplify a rational expression, factor both the numerator and the denominator as much as possible, then cancel out any common factors of the numerator and denominator, and then simplify the expression and rewrite it as a new rational expression.
