−2x−12

2(x

2

−x−6)

x

2

−3x+2x−6

x(x−3)+2(x−3)

(x−3)(x+2)

x−3=0orx+2=0

x=3orx=−2

Answer 2

Answer:

$2x(2x - 4) + 3(2x - 4) \\ 2x {}^{2} - 8x + 6x - 12 \\ 2x {}^{2} - 2x - 12 \\ 2(x {}^{2} - x - 6) \\ x {}^{2} - 3x + 2x - 6 \\ x(x - 3) + 2(x - 3) \\ (x - 3)(x + 2) \\ x - 3 = 0 \: or \: x + 2 = 0 \\ x = 3 \: or \: x = - 2$
