Hey guys I'm wondering if someone could hep me solve this integral. I've been working at it for a few days now (as part of a project I'm doing over the summer) and have gotten stuck. I think I need to make some substitution but I cant see what it is to make.(adsbygoogle = window.adsbygoogle || []).push({});

[tex]-\int\frac{dI}{I(R+BI+CI^2)}[/tex]

I decomposed using partial fractions and reduced it to this:

[tex]-\frac{1}{R}\int{\frac{dI}{I}+\frac{(CI+B)dI}{R+BI+CI^2}}[/tex]

I think I need to make another substitution here for the right-hand part of the integral. Simple U substitution doesn't work but I'm not sure of another method that would help. I tried completing the square for the polynomial on the bottom but that didn't seem to help.

Any help would be really appreciated! Thanks
