Complete the square to solve 3x2 + 12x = 9.

Anuta_ua [19.1K]

Answer:

C) x = -2 ± $\sqrt{7}$

Step-by-step explanation:

3x² + 12x - 9 = 0

divide through by 3

x² + 4x - 3 = 0

add 3 to each side

x² + 4x = 3

divide 4 in half and square it; add it to each side of equation

x² + 4x + 4 = 3 + 4

(x + 2)² = 7

x + 2 = $\sqrt{7}$

x = -2 ± $\sqrt{7}$
