Question

Which polynomial is a quintic binomial?

options:
x4 + 2x3 − x2 + 7x + 11
x2 + 4x
3x5 + 2
5x2 − 2x + 1

Answer 1

3x5 + 2

Explanation:

Answer 2

quintic polynomial is always ax^5+bx^4+cx^3+dx²+ex+f
quintic (the degree is 5)
binomial means the coefficients b, c, d, e are zero
so it is x^5+ f
so the answer is 3x5 + 2
