so i'm having problems with the coefficients in this problem.(adsbygoogle = window.adsbygoogle || []).push({});

[tex]\int[/tex](10z+8/z^2-8z+41)dz

i know that the main chunk is

(a)ln|(z-4)^2+25|+(b)arctan((z-4)/5)

a and b are 5 and 32/5 respectively

the problem is i can't seem to split up the top so that the first portion is the derivitive of the bottom and that the other top is the right constant.
