F.O.I.L

Today we learned a new, and easy way to multiply with binomials using FOIL.
F = First O = Outside I = Inside L = Last

eg. (h - 7)(h - 8)

First = (h - 7)(h - 8)
= h2 - 8h - 7h + 56
Outside = (h - 7)(h - 8)
= h2 -8h - 7h + 56
Inside = (h - 7)(h - 8)
= h2 -8h - 7h + 56
Last = (h - 7)(h - 8)
= h2 -8h - 7h + 56
_________________________________
= h2 - 8h - 7h + 56
= h2 -15h + 56

That's how easy these problems can be using FOIL. After Ms.Armstrong showed us how to use F.O.I.L. she handed each of us a card. Where one person would read an expression, and another person would say "I HAVE" if they have the answer to the question. Then they would say what they have, and turn the card. And then they would say a question themselves and someone else would now have to say what they have.. and so on and so on. It's a pretty fun game we should play it more often, Ms.Armstrong. =D

You did a fantastic job of describing the FOIL method...but don't forget that the term FOIL is not really used anymore. Now we call it Distributive Property because it works for polynomials of any size.
