User: Solve by graphing. x2 +2x - 8 = 0 A. –2, 4 B. 2, –4 C. 2, –4 D. –2, 4

Weegy: x^2 + 2x - 8 = 0
(x - 2)(x + 4) = 0
x - 2 = 0 or x + 4 = 0
x =2 or x = -4

User: What is the expression in factored form? 9x2 - 12x + 4 A. (3x - 2)2 B. (-3x + 2)(3x - 2) C. (3x + 2)2 D. (-3x - 2)2

Weegy: 9x2 - 12x + 4 = (3x - 2)^2
