Karissa Acevedo · Answer 1

Let's think about it for a sec. It can't be A for obvious reasons. Now let's think what makes (X+3) (X-2) ? the obvious answer is B, but don't be fooled. The zeros would be 2 (X-3) (X-2) which doesn't make sense. It can't be D because the zeros of that (after solving is) (x-6) (x-2) which doesnt make sense.

therefore the answer is B. you can always just graph it too.
