Review of Radicals and Quadratic Equations Lesson 9.1

Simplify Radical Expressions: = = = 4

(3 )2)2 = 33 = 63 Try: = = 3 or 1. 2.

Quadratic Equations Method 1: Solve for x (remember you will have ± in your answer) x = 25 x 2 = 16 x = ± 4

Method 2: Factoring x = 25 x = 0 (x-4)(x+4) = 0 (factor) x-4 = 0 or x+4=0 x = ± 4 Notice that with either method you get the same answer.

Try this one: x 2 = (5 ) 2 + ( ) x 2 = x =
