Question: factorization of long expression

December 11 2011 mnhoff 13


I have a long expression which I want to factor optimally.  If I can cancel terms in the numerator and denominator, great, and if not, I just want to reduce the size as best possible.  Maybe there will be terms such as

(x12 + x32 + y12 +y32)*(x22 + x42 + y22 + y42)

which I see when factoring the denominator by hand.  Here's the worksheet, the final expression 'rsoln' is to be factored:
