comment If $g^2 = e$ for all $g \in G$, then $G$ is abelian
$$a,b \in G \implies ab \in G$$

Because $ab$ is in the group since $a,b$ are in the group. And the property $g^2 = e$ holds foe very element of $g$. In particular, it must hold for $g = ab$

yes. the goal is to show this $z_0$ is actually a root of $p$.

comment How do I figure out if a 'function is odd or even'?
sure. For example, suppose $f(x) = x^2$. Since $f(-x) = (-x)^2 = (-x)(-x)= x^2 = f(x)$, we conclude that $f(x) = x^2$ is even.
