Quadratic Equation – equation that can be written in the form ax 2 + bx + c = 0 Two ways to solve, right now. 1. Factor and set = 0 2. Quadratic formula

Given: FE = FG 18x 2 – 3x x 2 – 3x – 18 = 0 (x – 6)(x + 3) = 0 x – 6 = 0 x + 3 = 0 x = 6 x = – 3 1x 2 – 3x – 18 = 01a1a – 3 b – 18 c x 2 – 3x = 18
