hi,
I have a very simple expression:
-(y*(G2-G1)+x*(-G2-G1)-n)/2
and I want to transform it in a form like:
(G1-G2)y (G2+G1)x n
------------- + --------- + ----
2 2 2
It looks simple, I've tried with ratsimp(%,x,y)
but I cant figure out how to manage the sign and
the denominator,
could someone please help?
thanks
andrea
