Alright, Doug. I left this for a day and gave the other BBSers a chance. No one bit. So I'm biting.

I think the error lies in a division by zero. Somewhere around the simplify-by-factoring step is the algebraic equivalent of a divide-by-zero error. My brain is too screwed up right now to analyze it in detail, so I can't write up a proof right now.

Besides, I hhhhhhate algebra.

I'm with muzza: Make the bad man stop, mommy.
