The answer is:

[(x^2 + 7x + 6)/x(x+z)(x-z)

I don't understand how to get that! was the z a typo? even if it's supposed to be a 2 - I don't understand!

Factor 1/(x+2) out of each term and see what you get.

[1/(x+2)][12/(x-2) - (3-x)/x]

=[1/(x+2)][12x/x(x-2) - (3-x)(x-2)/x(x-2)]

={1/[(x-2)(x+2)]}[12x/x -(3-x)(x-2)/x]

={1/[(x-2)(x+2)]}[(x^2+ 7x +6)/x]

That is in the form of your answer (except for the typo "z" for 2), but it can be factored further.

= (x+6)(x+1)/[x(x-2)(x+2)]
