x^2 + 8x + 16 = 2

A and B

Step-by-step explanation:

Given

x² + 8x + 16 = 2 ( subtract 16 from both sides )

x² + 8x = - 14

To complete the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(4)x + 16 = - 14 + 16

(x + 4)² = 2 ( take the square root of both sides )

x + 4 = ± ( subtract 4 from both sides )

x = - 4 ± , that is

x = - 4 - → A

x = - 4 + → B
