y squared minus 9 (y*y)- 9 cannot be solved because there is no given value for 9.

y² - y - 6 = (y + 2)(y - 3)

(9y+2z)(y-3z)

You have to put your heart into it!

There are no rational factors.

y2-y-72 is an algebraic expression that can be factored as: (y+8)(y-9)

The factoring is as follows: x2 - y2 = (x + y) * (x - y)

it depends,if y = 0 the answer is -12 if y = 5 then the answer is 368

it is (x-y)(x-y) :)

y2-4y-32 = (y+4)(y-8) when factored

2y(y + 3)(y - 7)

A polynomial.

x^2 - y^2 - 4 is in its simplest form.

It is not clear what you want to solve for.

(y - 2)(y - 7)

(y - 8)(y - 2)

9x2 - 6xy + y2 - 81 = (3x - y)2 - 92 = (3x - y - 9)(3x - y + 9)

The answer? There is no "answer" There cannot be an answer because they are all different. In order to make calculations, the variables have to be the same. x squared, xy, y squared are the variables, and none of them match. Therefore your "answer" must look like this: 9x squared - 6xy + y squared - 81. Hope I Helped :D

9x2 - 6xy + y2 - 81 = (3x - y)2 - 81 = (3x - y - 9)*(3x - y + 9)

4(y - 3)(y + 3)

(x, y) = (-3, -3) or (3, 3)

(x - y)2 = x2 - 2xy + y2
