Answer:

D

Explanation:

To classify the polynomial, see how many terms it has. If there's one, it's called a monomial, if there's two, it's a binomial, and if it has three, then it's a trinomial. In this problem, we have three terms, so it will be a trinomial.

To find the degree, you are simply just looking for the highest exponent in the problem. In this trinomial, you have exponents of 2, 2, and 1. 2 would be the highest number in the list, so your degree is 2.

Hope this helps!
