x + 12x + 20 = (x + 10)(x + 2)
I would do this. Multiply through by -1 -1 ( -X^2 +12X +28 ) = X^2 -12X -28 (X+2)(X-14)
(2x - 3)(2x - 3)
-9x 2 -12x+5 =
No solution. Multiply second equation by 3 and get 12x + 6y = 0 but already stated 12x + 6y = 9...
x2 + 12x + 32 = (x + 4)(x + 8)
4x(4x^2 + 3x + 1)
(x + 8)(x + 4)
6.(x2 + 12x + 36) = 6.(x + 6)(x + 6)
x + 12x + 20 = (x + 10)(x + 2)
The GCF is 3x.
2(x + 4)(x - 10)
3x3+12x = 3x(x2+4)
-2x+12x+28=10x+28 ;Combining like factors2(5x+14) ; Factor out a two from both of them
30+12x = 6(5+2x)
(-2x3 - 2x2 + 12x) = -2x (x2 + x - 6) = -2x (x + 3) (x - 2)
(x + 4)(x + 8)
