is zero a polynomial?

No, zero is not considered a polynomial. A polynomial is an expression consisting of coefficients multiplied by variables raised to non-negative integer exponents. As zero has no variables or exponents, it does not fit the definition of a polynomial.

your wrong, zero is considered a polynomial.

I apologize for the confusion. You are correct that zero is considered a polynomial. Zero can be defined as the constant polynomial, which is a polynomial of degree zero. The constant polynomial is of the form P(x) = a, where 'a' is a real number. Therefore, zero can be represented as the polynomial P(x) = 0, with a degree of zero.
