Do you mean:

???

If so, use to write .

do the same for the denominator and cancel out like terms! - Oct 6th 2010, 09:34 PMbigwave
you may want to look at this

http://www.wolframalpha.com/input/?i=[{(x-y)^2-z^2}%2F{(x%2By)^2-z^2}]*[(x%2By-z)%2F(x-y%2Bz)]

doesn't look like its going to simplify too much... that is if OP is correct.. - Oct 7th 2010, 05:28 AMPR98That's it!
