The discriminant of the quadratic equation ax2+bx+c = 0 is the value of b2-4ac
When b2-4ac = 0 then there are 2 equal roots.
When b2-4ac > 0 then there are 2 different roots.
When b2-4ac < 0 then there are no roots at all.

No.
Is 2 a polynomial?
Yes, f(x) = 2 is a polynomial of degree 0 (because there are no x terms).
Is it possible to find the discriminant of a binomial?
A polynomial discriminant is defined in terms of the difference in the roots of the polynomial equation. Since a binomial has only one root, there is nothing to take its difference from and so in such a situation, the discriminant is a meaningless concept.
