What is a rational expression? A polynomial is an expression that consists of a sum of terms containing integer powers of x , like 3 x 2 − 6 x − 1 . A rational expression is simply a quotient of two polynomials.
Rational Expressions. An expression that is the ratio of two polynomials: It is just like a fraction, but with polynomials. Other Examples: Also. But Not. In General. A rational function is the ratio of two polynomials P (x) and Q (x) like this. f (x) = P (x) Q (x) Except that Q (x) cannot be zero (and anywhere that Q (x)=0 is undefined)

The quotient of two polynomial expressions is called a rational expression. We can apply the properties of fractions to rational expressions, such as simplifying the expressions by canceling common factors from the numerator and the denominator.
Rational Expression. more ... The ratio of two polynomials. It is "Rational" because one is divided by the other, like a ratio. Note: the polynomial we divide by cannot be zero. See: Polynomial.
