Some examples of rational expressions follow: The example \(\frac{x+3}{x-5}\) consists of linear expressions in both the numerator and denominator. Because the denominator contains a variable, this expression is not defined for all values of x.

A rational expression is an expression of the form P Q, where P and Q are both polyno­mials and Q never represents the zero polynomial. Rational Expression. A rational expression is an algebraic expression that can be written as the quotient of two polynomials. Examples 1–4 are rational expressions:

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. To do this, we first need to factor both the numerator and denominator. Let’s start with the ...

Rational expressions can be simplified by cancelling common factors in the numerator and denominator. See Example. We can multiply rational expressions by multiplying the numerators and multiplying the denominators. See Example. To divide rational expressions, multiply by the reciprocal of the second expression. See Example.

Simplifying Rational Expressions. A rational expression is said to be reduced to the lowest term or simplest form if \ (1\) is the only common factor of its numerator and denominator. To reduce rational expressions, we factorize the numerator and denominator and then find their common factors.
