Yes! Also, 0 is a polynomial.
No. A polynomial can have as many degrees as you like.
It is a polynomial if the square root is in a coefficient but not if it is applied to the variable. A polynomial can have only integer powers of the variable. Thus: sqrt(2)*x3 + 4*x + 3 is a polynomial expression but 2*x3 + 4*sqrt(x) + 3 is not.
A "root" of a polynomial is any value which, when replaced for the variable, results in the polynomial evaluating to zero. For example, in the polynomial x2 - 9, if you replace "x" by 3, or by -3, the resulting expression is equal to zero.
The smallest is 0: the polynomial p(x) = 3, for example.
Since the question did not specify a rational polynomial, the answer is a polynomial of degree 3.
A trinomial
3
It is a numerical constant.
