<u>Answer:</u>
The degree of this polynomial is 3.
<u>Step-by-step explanation:</u>
The degree of a polynomial is the highest degree of its individual terms (also known as the monomials) which have a non-zero coefficient.
Here in this case, we have the following polynomial:
Each term has degree equal to the sum of the exponents on the variables. So for a term with two variables has the highest degree:
1 for x and 2 for y: 1 + 2 = 3
Therefore, the degree of this polynomial is 3.
