If your equation was 3x^2 - 12x = -12, then it is true you may factorize the terms as the previous contributer did before (3x - 6)(x - 2). But since there was no answer I will pick up where he/she left off and solve the equation using a somewhat different approach instead.
3x^2 - 12x = - 12
<=>
x^2 - 4x = - 4
<=>
(x-2)^2 - 4 = -4
<=>
(x-2)^2 = -4 + 4
<=>
(x-2)^2 = 0
<=>
x = 2

What times 8 equals 12?
To solve this, you should first write it as an equation (where 'x' is the unknown value):8x = 12Then you can solve for x:8x =12X = 12/8X=1.5
What is the value of the expression 9x2-12x 4 when x3?
If you mean: 9x squared-12x+4 when x = 3 Then it is: (9*3*3)-(12*3)+4 = 49
How do you solve 12 x - 5 equals 11 x plus 5?
12x - 5 = 11x + 5(1) add 5 to both sides:12x - 5 + 5 = 11x + 5 + 512x = 11x + 10(2) next subtract 11x from both sides:12x - 11x = 11x - 11x + 10x = 10
Thirty over twelve equals what over eighteen?
45 30/12 = x/18; 12x = 30 x 18; 12x = 540; x = 540 ÷ 12 = 45
How do you solve x squared plus 12x?
Factor. X^2 + 12X X(X + 12) = 0 X = 0 ------------- X + 12 = 0 X = - 12 --------------
How do you solve -12x equals 72?
-12x = 72 Divde both sides by -12 to find the value of x: x = -6
How do you factor 12x squared -7x -12?
It is: 12x2-7x-12 equals (4x+3)(3x-4) when factored
How do you solve 12x equals 24?
Divide both sides of the equation by 12: x = 2
How do you solve 12x plus 17 equals 7?
12x + 17 = 7 Subtract 17 from both sides: 12x = -10 Divide both sides by 12: x = -10/12 = -5/6
Solve for x. 9 equals 12 - 3x?
x . 9 =12-3x9x =12-3x9x+3x=1212x =12x =1
