How do you simplify rational expressions?

The simplification of rational expressions is explained

Solution:

Rational expressions are fractions that have a polynomial in the numerator, denominator, or both.

Rational expressions contain variables, they can be simplified in the same way that numerical fractions are simplified.

Steps to simplify rational expressions:

Let us see it with an example:

1) Look for factors that are common to the numerator & denominator

2) 3x is a common factor to the numerator & denominator. Note that it is clear that x ≠0

3) Cancel the common factor

4) If possible, look for other factors that are common to the numerator and denominator

5) After cancelling, you are left with

6) The final simplified rational expression is valid for all values of "x" except 0 and 1

We have to follow the same procedure for any rational expression.
