Answer: 
The expression is in the form 
where a = -25 and b = 18
==========================================================
Work Shown:
Let 
and then square both sides
We'll use both x and x^2 later on.
---------------------
The denominator is in the form 4+x. We'll multiply top and bottom by 4-x to then use the difference of squares rule. This will allow us to eliminate the square root in the denominator.
Therefore,
-------------------------------------
Checking the answer:
Use a calculator to find that,
We get the same decimal approximation, which helps confirm the correct answer.
Or you could use the idea that if M = N, then M-N = 0 to subtract the original expression M and the final result N. You should get 0 or very close to it.
