36X
It can't be simplified any more. That is the answer, 3*4X or 12x
(3x + 1) = -3 (x + 2x -1) (3x + 1) = -3 (3x - 1) 3x + 1 = -9x + 3 12x = 2 6x = 1 x = 0.16666666666666666666666666666666666666666666666666666666666666666666
If the equasion is 12x+6-8x-4x-3+12 then the answer is 15.
If you mean: 9x squared-12x+4 when x = 3 Then it is: (9*3*3)-(12*3)+4 = 49
0.3333
If you mean: (12x-3)(12x+3) then it is 144x^2 -9
x=-1 becaus: 12x+3=2x-7 10x+3=-7 (-2x) 10x=-10 (-3) x=-1 (divided by 10)
(6x^5 + 12x) / (-2x^-3) =[ (6x^5 + 12x) (x^3) ] / (-2) =(6x^8 + 12x^4) / (-2)=(3x^8 + 6x^4) =(3x^4)[ (x^4) + 2 ]
3x/(5-x)/3=4 3x/(5-x)=4X3 3x=12(5-x) 3x=60-12x 3x+12x=60 x=4
9726x ^ 8 = 1679616x12x ^ 3 = 1728x1679616 / 1728x = 972
(4*x*3)/2x=12x/2x=6
U do NT mention if it had a inequality,or value of x. So answer is 16x
6x3/12x = 6/12 * x3/x = 0.5*x2
x2+12x+5 = 3 x2+12x+5-3 = 0 x2+12x+2 = 0
2x/3 = 8 + 4x2x = 24 + 12x-24 = 10x-2.4 = x
8x-3+6x-1 = 12x+614x-4 = 12x+614x-12x = 6+42x = 10x = 5
