#### Answer

$3x(x+2)(x-2)$

#### Work Step by Step

We factor $3x^3-12x$. Factor out 3x to get: $3x(x^2-4)$ The term on the right in parentheses is a difference of two squares, and can be written as: $3x(x+2)(x-2)$ Upon further investigation, we see that it is completely factored, so the final answer is: $3x(x+2)(x-2)$
