The polynomial is .

To find the degree of polynomial, you must find the degree of each term or monomial.

The degree of a monomial is the sum of the exponents of all its variables.

The monomial is , so its degree .

The monomial is a nonzero constant, so its degree .

The degree of a polynomial is the greatest degree of any term in the polynomial.

In the above polynomial greatest degree is 4, so its degree is 4 and then it is called quartic polynomial.

In the above polynomial, one operation (addition) involves between two terms.

So it is called binomial.

The polynomial name according to degree and number of terms is quartic binomial.

The polynomial, name is quartic binomial.
