## Homework Statement

I have been asked to state the precise nature of the singularities at z=2 and z=-1/3 in

## Homework Equations

I know the laurent series is given by

## The Attempt at a Solution

I think I need to expand the series out into a laurent series around z=2 and z=-1/3 but I am really stuck on how to do this and would really appreciate a bit of help! From some examples I have seen I need to manipulate the denominator into a known series and then expand this but I am unsure of how to do that. Thanks
