so the question is what would A and B equal

this is my last question...i am stumped on a few of these..

I'll put you out of you're misery. Given an equation , You want to get something of the form , for some constant . (Note that .) When factored, this will become .

So in this case, so .

Break up the equation:

Factor and you're done: .

So and .

EDIT: You've already figured it out I see. Well, at least you have something to check it against now. - Sep 18th 2009, 04:28 PMfrozenflames
