Answer
$\text{Kind: }\text{
trinomial
}\\\text{Degree: }
3$
Work Step by Step
Since the +/- operator separates terms, the given polynomial expression, $
-5m^3+6m-9m^2
,$ has $
3
$ terms.
The degree of a polynomial is the highest degree among all the terms. The term that has the highest degree is the term $
-5m^3
.$
Hence, the given polynomial has the following characteristics:
\begin{array}{l}\require{cancel}
\text{Kind: }\text{
trinomial
}\\\text{Degree: }
3
.\end{array}
