Hi all, here's the deal I need help on a quiz question. The teacher said I can't get help with this. So Please don't tell me how to solve this just in case she sees this thread.(She's a stocker(Tmi) j/k) So, can someone just tell me if the awswer is right, or if I need to work on it.

$\displaystyle x^3-3x^2-54x$ That's the question I need to factor.

Here's my awswer, $\displaystyle x(x+6)(x-9)$ Is my awswer right or wrong?
