The answer to x2 - 2x - 4y2 - 4y =(x - 2y)(x - 2y - 2)
(2x - 7)(x + 1)
I assume you wish to simplify the expression (x - 2)/(3x + 9) . (2x + 6)/(2x - 4) = (x - 2)(2x + 6) / [(3x + 9)(2x - 4)] = 2(x - 2)(x + 3) / [6(x + 3)(x - 2)] = 1/3.
x - 2 = 0 if x = 2 So put x = 2 into 3x3 - 2x + 2 ie 24 - 4 + 2 = 22
x(3x - 2)
(x - 2)(2x + 3)
"minus negative x" means "plus x" (2x - 5)(x + 2) or (2x + 5)(x - 2) depending on what you really meant...
2
2(x + 2)(x - 2)(x2 + 2x + 4)(x2 - 2x + 4)
(y-2) (x+4)
The answer to x2 - 2x - 4y2 - 4y =(x - 2y)(x - 2y - 2)
It can be simplified to 2x^2 +x -6 and factored to (2x-3)(x+2)
X=27
It can be simplified to: 2x+2
(2x - 3)(x + 2)
(x - 2)(2x + 7)
x2 - 2x = x(x - 2)
