Rational Expressions A rational expression, also known as a rational function, is any expression or function which includes a polynomial in its numerator and denominator. In other words, a rational expression is one which contains fractions of polynomials. For example: The last equation also has a polynomial in the denominator, keeping in mind that thus becomes The... read more
