12x-17x = -5
12x - 2x = 10
(75y - 12x^2) * y = 75y^2 -12x^2y 75y - (12x^2 * y) = 75y -12x^2y
12x - 8 = 10x + 42x = 12x = 6
8x-3+6x-1 = 12x+614x-4 = 12x+614x-12x = 6+42x = 10x = 5
It could be either of them.
If you mean: (12x-3)(12x+3) then it is 144x^2 -9
GCF = 12x.24x = 2(12x)36x3 = 3x2(12x)
2*2 - 12x +16 =0 4 - 12x +16 =0 -12x + 16 +4 =0 -12x + 20 =0 -12x = -20 x = 1.666666667
5/4x+7/12x is the same as 15/12x+7/12x = 21/12x
12x-17x = -5
12x - 2x = 10
12x+x = 13x
12x * 4x2 = 48x3
The equation is equivalent to: -3x2 - 12x - 1 = 0 [you could change signs to get 3x2 + 12x + 1 = 0 but that is not required] The discriminant is (-12)2 - 4*(-3)(-1) = 144 - 12 = 132
12x-4y+9z+2y =12x-2y+9z
3x multiplied by (12x plus 9) is:3x(12x + 9)= (3x * 12x) + (3x * 9)= 36x2 + 27x
