You're multiplying the addend by ((x+4)/(x+4)) and the second addend by ((x-2)/(x-2)). You've got that part right! So now both addends have a common denominator: (x+4)(x-2).

So now you can add the numerators together: ((2x-5)(x+4))+((x-8)(x-2)) and that's all over (x-2)(x+4). Now you're going to forget all about the denominator and focus on that numerator.

You need to FOIL both (2x-5)(x+4) and (x-8)(x-2) and then add everything together. Once you've simplified that, put it over (x-2)(x+4) and you'll have your answer.
