The expression you provided is:

$9 - 6v + v^2$

This is a quadratic expression written in terms of $v$. Here's its breakdown:

1. $v^2$ is a quadratic term.
2. $-6v$ is a linear term.
3. $9$ is a constant term.

The expression is already simplified. If you need further operations like factoring, finding roots, or analyzing its graph, let me know.

Would you like me to go into more detail on any of these aspects?

Here are 5 related questions you might find interesting:
