Algebra 1 Ch.10 Notes Page 81 P Factoring to Solve Quadratic Equations
Zero Product Property If ab = 0, then a = 0 or b = 0What can x = to give you a zero in part of the problem??? (x + 5)(2x - 6) = 0 (x + 7)(x - 4) = 0 (3x - 6)(4x + 2) = 0
x2 - 8x - 48 = 0 x2 + 6x + 8 = 0 Solving by Factoring1. Factor (Mult. to ac and Add to b) 2. Use Zero product property to find zeros x2 + 6x + 8 = 0 x2 - 8x - 48 = 0
2x2 - 5x = 88 x2 - 12x = -36 Solving by Factoring1. Factor (Mult. to ac and Add to b) 2. Use Zero product property to find zeros 2x2 - 5x = 88 x2 - 12x = -36
y = x2 + x - 2 y = -x + 1 Substitution ActivityUse Substitution and Factoring to solve this system of equations... Where do the equations Cross? (Without Graphing) y = x2 + x - 2 y = -x + 1
