Write the polynomial in standard form. Then identify the polynomial by the number of terms.

Answer:
A
Step-by-step explanation:
Writing a polynomial in standard form involves arranging all the terms with the highest powered term first
In the given expression, the highest powered term is [tex]7b^3[/tex], so that would come first, and then [tex]-3b^2[/tex]
So we can write:
[tex]7b^3-3b^2[/tex]
A binomial is when there are 2 terms in the polynomial and a monomial is when there is 1 term.
Clearly we see that this has 2 terms and hence a binomial.
Answer choice A is correct.
