    Well I presume they are explaining it like you would destribute the negative in front of the first part of the problem through it.

    What part don't you understand? The part where I factored the numerator or the factorization of the denominator?

    Take the denominator which is 3x-12 and factor out a 3 and post what you get.

    NO!! When you write the factors of something, they must multiply back to the original expression.
