Best Answer

That depends on the values of the polynomial but in general:-

If the discriminant is greater than zero it has 2 solutions

If the discriminant is equal to zero then it has 2 equal solutions

If the discriminant is less than zero it has no solutions

The discriminant polynomial is always [ b2 - 4ac ]. In any given expression, it's a number. In this expression, the number is zero, indicating that the expression is a square.

We can't answer that without knowing what the polynomial is.

There is no polynomial below.(Although I'll bet there was one wherever you copied the question from.)

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.
