Question

Classify the polynomial by its degree and number of

terms.
-4x³ - 5x² - 1
O quadratic trinomial
O quartic binomial
O cubic trinomial
O quartic trinomial

Answer 1

Explanation:

The given polynomial is a cubic trinomial.

let us see how it becomes a cubic trinomial. let's discuss the degree first. The degree of a polynomial is the highest power of the variable in a polynomial. in this given polynomial there are two degrees i.e. 3 and 2. Since 3 is greater than 2 we will take 3 as the polynomial degree. The number of terms in the given polynomial is 3 ( 2 variable terms and 1 constant term) hence it becomes a trinomial.
