# Adding and Subtracting Rational Expressions with Unlike Denominators Worksheet

A rational expression is a quotient of two polynomials, a fraction whose numerator and denominator are polynomials. Polynomials are expressions in algebra that contain variables and coefficients. Two rational expressions with the same denominator can be added or subtracted by adding or subtracting the numerators and writing the resulting expression over the common denominator. When denominators differ, they must be changed to be similar. In other words, a common denominator must be identified.
