8x + 8 x - 1

______ X _______

^{X2}- 2x + 1 2x + 2

And don't say anything like, "I'm not doing your homework for you" or anything stupid like that. I just want to know how to do it, not the answer.

[tex]\frac{A}{B} \times \frac{C}{D} = \frac{A \times C}{B \times D}[/tex]

Does that help?

So if A/B x C/D => A x D=B x C

So:

8x + 8 x - 1

______ X _______

X2 - 2x + 1 2x + 2

(Yeah, I just copied that. I'm assuming that B has an x

(8x + 8)(2x+2)=(x

Now combine like terms, and solve for x. You will probably have to factor.

You're thinking of: if A/B = C/D, then A x D = B x CYou must cross multiply, if I'm looking at this correctly.

So if A/B x C/D => A x D=B x C

This may or may not be what the OP meant.
