A rational expression defined as the expression such that it can be expressed as the quotient or fraction p/q or simply quotient of two polynomials. A rational expression is the same as how we simplify the fractions. The only difference is of having polynomials in the expression.
Solved Example on Rational Expressions
Simplify given rational expressions (x + 3)^{3} and (x + 3)
Solution:
= (x + 3)^{3} / (x + 3)
= (x + 3)^{2}
= x^{2} + 6x + 9
Similarly, you can use the rational expressions calculator and simplify the given rational expressions:

4x^{2} and 3x^{3}

7x^{2} and 3x
