Question

Factor completely 3x^3 - 12x

Answer 1

`3 x^(3) -12x`

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


`3x( x^(2) -4)`

We can factor further, giving us the answer of:


`3x( x+2)(x-2)`

Answer 2

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

3x ( x^2 - 4)

And, that's your answer.
