Give the degree and classify the polynomial by the number of terms.

-x² + 3x - 4

A. degree: 2; trinomial

B. degree: 3; binomial

C. degree: 3; trinomial

D. degree: 2; binomial

A. degree: 2; trinomial

Step-by-step 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
