Question

identify the type of polynomial for ( x^{4}+2x^{3}-x^{2}+4 ).
a. binomial
b. trinomial
c. monomial
d. polynomial with four terms

Explanation:

A monomial has 1 term, binomial has 2 terms, trinomial has 3 terms. The given expression $x^4 + 2x^3 - x^2 + 4$ has 4 distinct terms: $x^4$, $2x^3$, $-x^2$, and $4$, so it is a polynomial with four terms.

Answer:

d. Polynomial with four terms
