I was just introduced to this concept and I have solved a few problems, but I haven't come across any with denominators to a raised power yet.

∫ 1 / [(x+7)(x^2+4)] dx

I would appreciate any directed help.

1. from the initial state I have broken the fraction into two assuming that (x+7)(x^2+4) is the common denominator where A and B are unknown.

∫ A / (x+7) + B / (x^2+4)

B / (x^2+4) has me confused

as I said before, I have not come across denominators to a raised power before and understand that the numerator needs to be raised to one power less, but what this looks like I don't know.
