Answer:
A. degree: 2; trinomial
Explanation:
The degree of a polynomial is the highest degree of a single term. In this example, the highest degree is 2 (-x^2) so the degree of the polynomial is 2. If a term has more than one variable, add all the degrees in the term (e.g. a polynomial with x^2y^3 has a degree of 5).
The classification of a polynomial depends on how many terms there are.
- Monomial: 1 term
- Binomial: 2 terms
- Trinomial: 3 terms
