Order of roots for a polynomial $P\in\mathbb{F}_p[T]$

Let $P\in\mathbb{F}_p[T]$ (not supposed irreducible). All roots $\xi$ of $P$ have a certain order $k$ such that $\xi^k=1$. Question: is it possible to know the order of the roots of the given polynomi …

Order of elements $\gamma$ and $1-\gamma$ in $\mathbb{F}_q$

I'd like to find if possible the orders possible for $1-\gamma$ given a $\gamma\in\mathbb{F}_q$ of given order $\mathcal{o}$ (where $q=p^f$). Which is clear is that these order have the same degree (d …
