What is Rational Expression?

A rational expression is a fraction in which the numerator and denominator are polynomials. The denominator of the rational expression can never have zero value. In other words, a rational expression is defined as an algebraic expression which can be written as a ratio of two polynomial expressions. For simplifying the rational expression, it is necessary to eliminate the common factors in both the numerator and denominator and find the Greatest Common Factor (GCF) of the factor.

An example to represent the rational expression is given below:

  • (x+3)/x

Standard Form

The standard form to represent the rational expression is given below:

Rational Expression = A(x)/B(x)

Where A(x) and B(x) are the polynomial expressions and B(x) ≠ 0

Frequently Asked Questions on Rational Expressions Calculator

Write a few examples of rational expressions?

  • (x2+5)/(x+2)
  • (x-1)/(x+2)
  • (x2-5x+6)/(x-3)

How do you simplify a rational expression?

To simplify a rational expression, take the common terms on both numerator and denominator, and eliminate it. Use the Greatest Common Factor (GCF) to accomplish the simplification of rational expressions.

Write the difference between rational expressions and equations?

A rational expression is a mathematical phrase that contains numbers, variables, and operators to express the value. But, an equation is a Mathematical description wherein two expressions are equal to each other.
