What is a Rational Expression?

A rational expression can be defined as the quotient of two polynomials, that is, a fraction having its numerator and denominator expressed as polynomials.

Given the expression, 15 - x / x - 10, when x = 5, substitute the value of x into the rational expression:

15 - 5 / 5 - 10

10/-5

= -2.

The value of the rational expression is: -2.
