Answer:
Trinomial
Step-by-step explanation:
we know that
A polynomial can be classified by its number of terms.
A polynomial with one term is called monomial, a polynomial with two terms is called a binomial, and a polynomial with three terms is called a trinomial
In this problem we have
[tex]9x^3+2x^2+4x[/tex]
This polynomial has three terms
therefore
Is a trinomial
