### What is Meant by Rational Expression?

In Mathematics, a rational expression is defined as an expression which is the ratio of two polynomials. Let p(x) and Q(x) be the two polynomials, then the rational expression f(x) is given as
f(x) = P(x)/ Q(x),
where Q(x) is not equal to zero
Example of a rational expression is (x + 9)/ (x+2)
