1. So I need to solve the following integral

∫1/(2+√x)

3. The attempt at a solution
By double integrating with u-substitution, I got to the following answer: 4+2√x-4ln(2+√x) + C

I can't find out where I go wrong, cause the answer is 2√x-4ln(2+√x), it has been a while, so maybe the +4 just adds to the constant?
