Find all the Laurent series for the below function around z=0.
f(z) = 3/(2+z-z^2)
I think the intervals are:
1: 0 < |z| < 1
2: 1 < |z| < 2
3: |z| > 2
Is that correct?

$\begingroup$ My question is that are these 3 intervals the correct intervals on which I have to find the Laurent series for the function? $\endgroup$– WinstonJun 10, 2017 at 20:46

$\begingroup$ The sets are not intervals. Each of them is an annulus. Other than that, you are right. $\endgroup$– José Carlos SantosJun 10, 2017 at 20:48
