Answer
degree = 3
Work Step by Step
The degree of a polynomial s equal to the degree of the term with the highest degree,
The degree of a term with one variable is equal to the exponent of the variable.
Thus, the terms of the given polynomial have the following degrees:
First term: $3$
Second Term: $2$
Third Term: $0$ ( the degree of a constant is 0)
The highest degree is 3, therefore the degree of the polynomial is $3$.
