Could someone please explain this problem to me?
I will show you what I have so far.
Perform the indicated operations and simplify.
w2/w7w+1/w+7+w77/w^249
I made it to this step and now I can't figure out what to do next.
w^2+w14/(w+7)(w7) + w^26w7/(w+7)(w7) + w77/(w+7)(w7)=(w^2+w14)+(w^26w7)+(w77)/(w+7)(w7)= 4w98/(w+7)(w7).
This is where I'm lost at. I can't seem to figure out the end result.
Thanks for the help.

Only after looking at your solution was I able to figure that your really meant....
(w2)/(w7)  (w+1)/(w+7) + (w77)/(w^249)
= [(w^2 + 5w  14)  (w^2  6w  7) + w77 ]/[(w+7)(w7)]
= (12w  84)/[(w+7)(w7)]
= 12(w7)/[(w+7)(w7)]
= 12/(w+7) , w ≠ 7 (or else we divided by zero) 
Thanks but I figured out where I made my mistake and got the answer.
