Best ResponseYou've already chosen the best response.0NO! What you do is square root the first and last terms (only works when you can do this evenly and when the terms are being subtracted)

Best ResponseYou've already chosen the best response.0Your two factors are those two square roots, except one is plus and one is minus.
