Stuck on Maths question (A level)

[From: ] [author: ] [Date: 11-10-30] [Hit: ]
because it says simplify it - but to me,Please help! Thanks in advance.-I got stuck on this,You can be done here, because each of the remaining expressions in the radicals cant really be simplified any more.......
Simplify (2+√5) / (3-√7)

I got stuck on this, I tried to rationalise the denominator and got: (6+2√7+3√5+√35) / 2

Then I divided by 2, and got: 3+√7+1.5√5+.5√35

Basically I have no idea what to do from here, because it says simplify it - but to me, it looks like I have complicated it even more than it was in its original form :L

Please help! Thanks in advance.

You can be done here, because each of the remaining expressions in the radicals can't really be simplified any more.
That is, 7 and 5 are prime, so 7 and 5 each have no perfect squares for divisors. 35's divisors are {1, 5, 7, 35}, none of which are perfect squares.
