You factor by the GCF (Greatest Common Factor). So, the equation would look like this:

3x ( x^2 - 4)

And, that's your answer.

[tex]3 x^{3} -12x[/tex]

The greatest common factor we can pull out is 3x, leaving us with this:

[tex]3x( x^{2} -4)[/tex]

We can factor further, giving us the answer of:

[tex]3x( x+2)(x-2)[/tex]
