Responses

A. The degree of the polynomial is 3.
A. The degree of the polynomial is 3.

B. Written in standard form, the polynomial is 7x4 + x3 + 2x2 − 3.
B. Written in standard form, the polynomial is 7 x 4 + x 3 + 2 x 2 − 3.

C. The polynomial is a binomial.
C. The polynomial is a binomial.

D. The leading coefficient is 1.

Answer 1

B. Written in standard form the polynomial is 7x^4 + x^3 + 2x^2 − 3.

(Highest power is 4, so the degree is 4 and the leading coefficient is 7; it has four terms, not two.)
