# Rationalizing the Denominator

Rationalize the denominator:

Solution

To eliminate the square root, we can multiply by the conjugate of

 We multiply by 1 written in the form Multiply the numerators and multiply the denominators. In the numerator, use the Distributive Property. In the denominator, use the FOIL method. In the denominator, combine like terms. We normally do not leave a negative number in the denominator. Therefore, multiply by 1 in the form Multiply the numerators and multiply the denominators.
