y^3 + y^2 - 6 (y+2) (y-3) i think
There are no rational factors.
it is (x-y)(x-y) :)
The factoring is as follows: x2 - y2 = (x + y) * (x - y)
2y(y + 3)(y - 7)
(y - 2)(y - 7)
4(y - 3)(y + 3)
x^2 - y^2 - 4 is in its simplest form.
(3y - 5)(y + 5)
y² - y all depends on the value of y. If you want to factor the expression, then we have y(y - 1)
9x2 - 6xy + y2 - 81 = (3x - y)2 - 81 = (3x - y - 9)*(3x - y + 9)
(x - y)(x + y)
