Answer:
Monomial.
Step-by-step explanation:
We have been given an expression . We are asked to identify our given expression as monomial, binomial, or trinomial.
We can see that an expression with single term is known as monomial, expression with two terms is known as binomial and expression with 3 three terms is known as trinomial.
Upon looking at our given expression, we can see that our expression has two terms. But we need to be careful as in 2nd term y is being multiplied by 0, which will result as 0.
Therefore, our given expression is monomial.
