5.6.1 – Square Root Method

Recall, we solved “quadratic equations” when we set a polynomial equation equal to 0 Example. x 2 + 5x + 6 = 0

In some cases, we can use a special method to solve the equations So far we have used factoring, calculators, quadratic equation

Properties of Square Roots

Simplifying/Rationalizing To simplify a radical expression, we will look for any perfect square roots we could pull out Perfect Roots = 1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 121,… If there are no perfect roots to pull out, then the expression is considered simplified

Rationalizing
