2x - x = x
(x - 2)(2x + 3)
It is -2x
2x(x−6)(x+1)
"minus negative x" means "plus x" (2x - 5)(x + 2) or (2x + 5)(x - 2) depending on what you really meant...
2x - 2x = 0
2x - 3x = -x
2x squared minus 5x minus 3 factored is (2x+1)(x-3).
The answer to x2 - 2x - 4y2 - 4y =(x - 2y)(x - 2y - 2)
x + 1
X=27
6 - x + 7 - 3x - 5 = -2x - 10 ∴ x + 3x - 2x = 6 + 7 - 5 + 10 ∴ 2x = 18 ∴ x = 9
