    Have you learned about `Binomial Theorem`? :) If not, that's ok, expanding out three sets of brackets shouldn't be too bad.

    |dw:1443316909081:dw|We'll take the 2x from the first set of brackets and distribute it to each term in the second set of brackets. We do the same with the 3y from the first set of brackets. This method is often referred to as FOIL ( I can't remember what that stands for lol )

    So we'll end up with 4 terms in total. The first of which (starting from the bottom) is \(\large\rm 6xy\) ya? :) Can you get the other terms?

    @zepdrix do you draw in the DRAW area with a i-pad or one of those pen tablets or something?... looks neat. Always wondered if those tablets worked here.

    Ya I have a Wacom Bamboo Tablet thingy :) It's a lot more difficult to use that I anticipated, I probably wouldn't recommend buying one, unless you're getting it for like drawing art stuff, or for playing Osu XD
