Question

Solve for x in the equation x2 + 4x-4-8.
O x= -6 or x = 2
O x=-2+2V2
O x = -2 or x = 6
O x=2+25

Answer 1

Answer:

O x = - 6 or x = 2

Step-by-step explanation:

x² + 4x - 4 - 8 = 0

x² + 4x - 12 = 0

x² + 6x - 2x - 12 = 0

x(x + 6)x - 2(x + 6) = 0

(x + 6) (x - 2) = 0

x + 6 = 0 or x - 2 = 0

x = - 6 or x = 2

Thus, x = - 6 or x = 2
