3x²+12x+12=0

Taking 3 CommOn from Equation

3(x²+4x+4)=0

x²+4x+4

x²+2x+2x+4

x(x+2)+2(x+4)

(x+2)(x+2)

Thanks!!!

________________________

$3{x}^{2} + 12x + 12 = 0 \\ \\ Splitting\: middle\: term \\ \\ 3{x}^{2} + 6x + 6x + 12 = 0 \\ \\ 3x(x + 2) + 6(x + 2) = 0 \\ \\ x + 2 = 0 , 3x + 6 = 0 \\ \\ x = - 2 , x = \frac{-6}{3} \\ \\ x = - 2 , x = - 2$
