Integrate: dx/sqrt(x^2+2x +5)

2. Relevant equations

refer to above

3. The attempt at a solution

I can integrate the equation dx/sqrt(1+x^2) using the rules

cosh^2 u - sinh^2 u = 1

cosh^2 u = 1+sinh^2 u

but i dont know where to start with this question because of the 2x + 5 in the denomentor. Could someone please point me in the right direction.
