Look at the equation - anything multplied by zero is zero.

I second the 2. (I didn't try the other two possibilities)

yes, I know that's solved not expanded but I plugged some numbers in a couple of the "solutions" on the first page and they don't give the same results as the initial question. So maybe they're incorrect if the expanded answer is just a variation on that question? Just a thought, it's been a long time since I've been near those!...
