8-10.

Factor each of the following expressions.

$x^3-xy^2$
Hint (a):
Factor an ' $x$ ' out first. Then factor again.

$x^3+xy^2$
Hint (b):
Factor an ' $x$ ' out first. Can you factor again?
More Help (b):
You cannot factor again. This is NOT a difference of two squares.

$4x^2\sqrt{x^2+y^2}-4\left(x^2+y^2\right)^{3/2}$
Step 1(c):
Change the square root part of the first term to exponential notation. $4x^{2}(x^{2}+y^{2})^{1/2}-4(x^{2}+y^{2})^{3/2}$
