    Paulo ... go read your book, seriously. Most of the problems you've posted are similar and have the same method for solving this problem.

    The only thing i can't figure out with this question is how to get a common donominator with x. and btw i saw what i did wrong with the other question like this one but this is different as the denom has x's...
