Your quadratic equation has
The discriminant of a quadratic equation can only give us information about an equation of the form:
Because the highest degree of this polynomial is 2, it must have no more than 2 solutions.
The discriminant is simply the stuff underneath the square root symbol (
If the discriminant,
Therefore, your quadratic equation must have
