Which polynomial is a quintic binomial?

x^4 + 2x^3 - x^2 + 7x + 11

x^2 + 4x

3x^5 + 2

5x^2 - 2x + 1

Polynomial A : x^4 + 2 x³ - x² + 7 x + 11 has a Quartic degree.

Polynomial B : x² + 4 x is a Quadratic binomial.

Polynomial D : 5 x² - 2 x + 4 has a Quadratic degree.

Answer:

Polynomial D : 3 x^5 + 2 is a Quintic binomial
