Answer
polynomial of degree 2.
Work Step by Step
Polynomials consist of one or more monomials and have the form:
$$a_nx^n+a_{n-1}x^{n-1}+...+ a_1x+a_0$$
where $x$ is the variable, $a_n$ is the leading coefficient, and $n$ is a non-negative integer called the degree.
We see that the given expression $10z^2+z$ is a polynomial of degree 2.
