I've got an integral like below $\int \frac{\mathrm{d}x}{2 + \sqrt{x}}.$
I use a substitution like this $t = 2 + \sqrt{x}$, but an answer looks a bit different. What do you suggest?

The term $4$ in your answer is a constant and therefore can/should be incorporated into the constant of integration $C$.
