To reduce a radical factor out the largest perfect square & simplify. Simplifying Radicals To reduce a radical factor out the largest perfect square & simplify.

Today we are going to look at how to simplify roots

Examples

Examples

Examples

Rationalizing the Denominator It is improper to have a radical in the denominator of a fraction. If this happens multiply both the numerator & the denominator by the radical to eliminate the radical in the denominator.

Examples

We can use roots to help us solve

Radical Equations Simplify until the square term is on one side and everything else is on the other. Take the square root of both sides then solve.
