Expansion errr

  1. Apr 12, 2010 #1
    1. The problem statement, all variables and given/known data
    Basically i did these problems quite awhile back maybe 7 months ago lol its sort of dull now..

    Question is: 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.

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