Question

Classify the expression as a monomial, a binomial, a trinomial, or not a polynomial.

Answer 1

By definition, a trinomial is an algebraic expression that has 3 terms.

In the given polynomial:

$-4b^4+5m^3+2z$

We can identify the following terms:

$\begin{gathered} -4b^4\text{ First term} \\ +5m^3\text{ Second term} \\ +2z\text{ Third term} \end{gathered}$

Then, we can say it is a trinomial.
