Verified answer

x^2+4x -12=0

x^2 +2x - 6x -12=0

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

so, [x+2] [x-2]=0

x =2

x=-2

x2 + 4x - 12 = 0

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

x=2 or x=-6

x² + 4x - 12 = 0

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

x = - 6 , x = 2

X^2 +4X -12=0

X^2 +6X -2X -12=0

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

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

X=-6 0R X=2

:)

X2 – 12 = -4x

X2 + 4x - 12

(X + 6)(X - 2)

x2+4x-12 = 0

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

x = {-6,2}
