Factor out x^2 from each term.
x^3 - 2x^2y = x^2(x - 2y).

x^3-(2x^2)y?
im not so great at this myself, but u need to find the lcm of either side of the subtraction sign. i think that is x^2.
so divide both sides by this number, and u get: x-2y. i hope thats right.

x^3-2x^2 y the answer would be x^2(x-2y)
