Best ResponseYou've already chosen the best response.0If you FOIL it: First: a*a = a² Outer: a*(b) = ab Inner: b*a = ab Last: b*(b) = b² Add up everything: a² + ab + ab + b². What do you think about the middle two terms?

Best ResponseYou've already chosen the best response.0The middle two terms cancel: ab+ab=0, so you are left with only a²b². So never a trinomial; there are only two terms.
