Complex integration

Hello folks.

I'm probably missing something really simple, but how do i calculate the integral of (5z^4 -3)/(z^5 - 3z +1) around the unit disk?

I'm trying to find the number of zeros inside it, you see.

Thanks!

I'd personally use the residue theorem :smile:
I take it this is 2nd year stuff?
