Question

Which of the following is a binomial?

A. b²-14
B. x²
C. s⁴-s+12
D. f³+f²-f+16

Answer 1

Binomial is an algebraic expression of the sum or the difference of two terms so:

So option A. has two terms (b and -14)
Option B has one term (X multiplied by X)

Option C has three terms (s^4, -s and +12; NOTE that s^4 and -s are not the same terms)

similarly,

Option D has four terms

therefore only option A is a binomial!

Answer 2

Binomial: A polynomial that is the sum of two terms, each of which are monomials. The answer here would be A. b² - 14, because it is comprised of two terms. Answer B is a monomial because it only has ONE term, C is a trinomial because it has three terms, and D. is a multinomial, or a polynomial because it has more than three terms. Hope that helps!
