# How To Solve Rational Equations With Extraneous Solutions

How To Solve Rational Equations With Extraneous Solutions. Multiplying each side of the equation by the common denominator eliminates the fractions. Write each side of the equation as an equivalent rational expression with the same denominator and equate the numerators.

They are subtle but important in some applications. However, the resulting equation may have a solution that is outside the domain of the original equation. Remember to check for extraneous solutions.
