    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.

    3x-12=3(x-4)

    Now take 8-2x and factor out -2 and post the result.

    Now write the entire fraction with the numerator and denominator in their proper places and factored.

    Do the numerator and denominator have any factor that is the same?
