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
Answer: {2}
x . 9 =12-3x9x =12-3x9x+3x=1212x =12x =1
If you mean: 9x squared-12x+4 when x = 3 Then it is: (9*3*3)-(12*3)+4 = 49
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
45 30/12 = x/18; 12x = 30 x 18; 12x = 540; x = 540 ÷ 12 = 45
Oh, dude, you're hitting me with some math now? Okay, so, like, technically, 1.5 times 8 equals 12. But, like, who really needs to know that, right? Just use a calculator or something. Math is hard, man.
Factor. X^2 + 12X X(X + 12) = 0 X = 0 ------------- X + 12 = 0 X = - 12 --------------
-12x = 72 Divde both sides by -12 to find the value of x: x = -6
12x + 17 = 7 Subtract 17 from both sides: 12x = -10 Divide both sides by 12: x = -10/12 = -5/6
x . 9 =12-3x9x =12-3x9x+3x=1212x =12x =1
the answer is-10 = 12 +xx= -10-12x=-22this is the answerx= -22
It is x^2 + 12x or x(x + 12).
6*3-6*2-12x v v 18 - 12-12x v v 6-24x -6 -6 something like that..

You plug in the values of x and y and solve 12x + 16y = ? 12(1) + 16(2) = 12 + 32 = 44
When x = 5, 12x = 12*5 = 60.
12x-30=114 12x=114+30 x=144 / 12 therefore x=12
