Answer: The answer is a cubic binomial.
Step-by-step explanation: The given polynomial is

We are to write the truth about the above polynomial, its type, etc.
Since the polynomial contains two expressions (terms), so it is a binomial.
Also, the degree of both the terms
and
is 3.
We know that the degree of a polynomial is the highest degree among the terms that are present in the polynomial, so the degree of P(x, y) is 3.
Therefore, P(x, y) is a binomial of degree 3.
Thus, it is a cubic binomial.
