X^2 + 6x = - 9 User:
Which of the following equations shows the correct form of the equation x^2 + 10x + 25 = 16 if the zero product property is to be used?
(x + 5)(x + 5) = 16
(x + 1)(x + 9) = 0
(x - 1)(x - 9) = 0 User: 3x2 = 147

Respuesta :

x² + 10x + 25 = 16

x² + 10x + 25 - 16 = 0
x² + 10x + 9 = 0

(x + 1)(x + 9) = 0

x(x+9) + 1(x+9) = 0
x² + 9x + x + 9 = 0
x² + 10x + 9 = 0


(x + 1) = 0
x = -1

(x + 9) = 0
x = -9
