The nature of the roots of the quadratic can fall into one of three categories depending on the value of the discriminant :
means there are distinct real roots.
means there are equal real roots, or distinct real root.
means there are no real roots, but complex roots.
Since the discriminant is less than there are no real roots. Instead, there are two complex roots.
