Integral

[NYC]

Hi, I'm having trouble integrating: (x^2+4)/(x+1)(x^2+x+1)
I've tried breaking it apart, attempting partial fractions and also looking for inverse trigonometric relationships. I'm pretty sure that there is some combination of those factors in the answer to this integral. Any help would be greatly appreciated.
