8-4B Solving Quadratic Equations when the Leading Coefficient isn’t 1. X-Factor method If you factor out a GMF: before using the X figure, keep it, after.
Warm Up. y = 8x 2 – 16x -10 = roots a = 8, b = – 16, c = -10 Axis of symmetry = -b 2a x = -(-16) 2(8) = 1 y = 8(1) 2 – 16(1) -10 = -18 Vertex= minimum.
