@peterag I am happy with it. I just have not rewarded his answer, yet. You may and I will reward your answer. Thanks

@peterag No, and I do not think I can make it any simpler: encloses means surrounds. Have a look at this question and Christian's answer.

Also, what do you mean by "$z$ picks up a factor of $-1$"? Thanks

Just to clarity: $n(\gamma_0, z)$ is the winding number of $\gamma_0$ about $z$, correct?

@peterag What is your question? To enclose means to surround. To enclose two roots by $\gamma$ means to surround two roots by $\gamma$. Two of the roots are the interior points of $\gamma$ and the third is an exterior point of $\gamma$.

@peterag Suppose $e_1, e_2 \in \gamma$, $e_3 \not \in \gamma$, say, and $e_3 \not \in \partial \gamma$.
