Answer 1

Definitions:
A polynomial is monomial if it has exactly one term. It is called binomial if it has exactly two non-zero terms. A polynomial ​is a trinomial if it has exactly three non-zero terms.

The polynomial \[4a - 15 a^2\] has exactly two terms, i.e., 4a and \[- 15 a^2\].Therefore, it is a binomial.
