by completing the square the expression that is x^2+14 x +156 equals (x+A)^2+B
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.
