Rational Expression

Rational expressions are fractions that have a polynomial in the numerator, denominator, or both. Although rational expressions can seem complicated because they contain variables, they can be simplified using the techniques used to simplify expressions such as combined with techniques for factoring polynomials.

Simplifying Rational Expression

To simplify a rational expression, follow these steps:

  • Determine the domain. The excluded values are those values for the variable that result in the expression having a denominator of 0.
  • Factor the numerator and denominator.
  • Find common factors for the numerator and denominator and simplify.
