Question

Which polynomial is a binomial?
A. 2p^3-p
B. 6-2x^3-4x^2+x^5
C. x^2
D. 1-2x+5x^4

Answer 1

A is binomial. It has two terms: 2p^3 and p.

Answer 2

A.

A binomial is defined as a polynomial with two terms. Any "term" is a single power of a variable. For example, x^2 + x^3 is a binomial, but x^2 + x^2 is not. So, as we can see, A is the only binomial in this question.
