2. I get 15 sqrt of 13 on top then on bottm I get 169 - 3(sqrt 13)...which puts me back in the same boat as before...

You're not correctly cross multiplying.
Remember:
(a+b) * (c+d) = ac + ad + bc + bd
So with:
sqrt(x+2) = 1 + sqrt(x-5)
If you square both sides:
(x+2) = 1 + 2*sqrt(x-5) + (x-5)
You should be able to take it from there.
