Rational Expressions can be rewritten in a simplified form by canceling off any common numerical or variable factors.

Hope it helped : )

Answer:

A rational expression is a quotient between two polynomials. To write them in a simplified way, you can search the roots of the functions and see if you can cancel any part of the expression of the numerator with one of the denominator.

Explanation:

In other words, functions are factored to see if there are coindicent roots that can be canceled, here is an example:


f(x)=(x^(2) -4)/(x^(2) -3x+2) =((x+2)(x-2))/((x-1)(x-2)) =(x+2)/(x-1)

In this example, we can cancel the term (x-2), because it is both in the numerator and in the denominator. In this way we get a simplified expression.
