expansion errr

[ibysaiyan]

1. The problem statement, all variables and given/known data
Hi
Basically i did these problems quite awhile back maybe 7 months ago lol its sort of dull now..

Question is:http://i44.tinypic.com/2h3zn6q.png
2. Relevant equations

So do i first expand them or how? LOL i can do partials fractions and all but for some reason not these apparently easy to look problems.Thanks for your reply!

3. The attempt at a solution

Well you can expand them both, and that's pretty simple, but long an tedious. I imagine that the better way to do these involves the Binomial Theorem.

Hi
Thanks for the reply
So basically i just use binomial expansion and then compare the co-efficients..?
