Here's my work:
I get so confused when I have to manipulate radicals. Any ideas on what I can do to fix it?
Actually, I think I mistyped it into the forum.  Even though I mistyped it, I think it is still the same. I'm not sure where I'm going wrong with it. Is there a 'radical tutorial' website that'll be helpful?[/edit]
I know the denominator should eventually be a 2, but I just do see that happening at any time of simplifying the solution.
Okay, I think I understand. You were able to pull out the -1 and the -2 from the
In doing so, I have
Then solving the rest of the problem, it should look like:
-3 and 6 cancel out and I get my final answer of:
Is that correct?
 I seem to have a hard time doing this latex coding stuff. Please excuse me while I try to fix it.
[edit again] Okay, hopefully that fixed it.
