PLEASE HELP!

Okay I'm DESPERATE.

Can somebody please tell me what

n^3-64 divided by n-4 is?

And for x/x+2 - 4/x-2 - 1
is the answer 2(-3x+2)/(x-2)(x+2

n^3-64 is a difference of cubes: you should have an equation to factor it.

No, on the second one.

The common denominator is (x-2)(x+2) so

x(x-2) -4(x+2) -(x-2)(x+2) all that over the common denominator

First, u have to say what 'n' represents, then only u can figure out the equation....
