I am taking an algebra class this semester after a very long break from math. I'm having a little trouble remembering some things and so far reading my textbook hasn't been very helpful.

I have a problem that says "rationalize the denominator" and the problem is:

3 + √x / 3 - √x

I have come up with several different answers and I just need to know if I am on the right track. I multiplied both sides of the expression by the inverse of the denominator and used the FOIL method. I came up with 10√x^4 / √x^2 the last time I worked this expression out. Am I doing this correctly?
