the one that is what you get when you multiply 
$$(x-2)(x+3)(x-3)$$

http://www.wolframalpha.com/input/?i=%28x-2%29%28x%2B3%29%28x-3%29 hmm looks like it is none of these

anonymous · Answer

My bad it's 2,-3i, and 3i.

$$x^3-2x^2-9x+18$$ is what wolfram gets, and i would bet it is right

anonymous · Answer

oh well in that case it is what you get when you multiply 
$$(x-2)(x^2+9)$$

anonymous · Answer

$$x^3-2x^2+9x-18$$
