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.)

The discriminant is 0.
The discriminant is -7
The discriminant is 0.
The discriminant is 88.
52-4*7*1 = -3 The discriminant is less than zero so the quadratic equation will have no solutions.
The discriminant of the quadratic polynomial ax2 + bx + c is b2 - 4ac.
It is 40.
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.
