I don't know where to start with this problem.
I'm trying to evaluate the limit as x goes towards 7 of ((x+2)^(1/2)-3)/(x-7).
The answer is 1/6 according to my text.
Sorry, my latex skills are a bit rusty...

THanks.
If You multiply numerator and denominator by $\displaystyle \sqrt{x+2}+3$ , You will 'discover' that a confortable simplification is possible...
