x² + 4x - 12 = 0
(x + 6) (x - 2) = 0
x = - 6 , x = 2

This equation can be rewritten
x^2 + 4x -12 =0
=> (x+6)(x-2) = 0
so,
x= -6 or x=2

x^2 + 4x -12 = 0
(x + 6) (x - 2) = 0
x = - 6 or x = 2

x2 +4x =12
x2 +4x -12 = 0
(X+6)(X-2) = 0
X = -6 (1)
X = 2 (2)
X has two answers -6 and 2.

is the same as x^2+4x-12 which factors out to (x+6)(x-2)=0
set each equal to zero...
x=2, -6

im not sure what you are asking for but...
x^2+4x-12=0 factors to (x+6)(x-2)=0
so its roots or zeros are -6 and 2

~~~
x²+4x = 12
x²+4x -12 = 0
x²+6x-2x - 12 = 0
x(x+6) - 2 ( x + 6) = 0
(x+6)(x-2) = 0
x+6 = 0 therefore x = 0-6 = -6 ; x = -6
x -2 = 0 therefore x = 0-2 = 2 ; x = 2
x = 2 or -6
~~~
