In a quadratic equation AX^2+BX+C=0, the expression B^2-4AC is called the discriminant. If the discriminant is greater than zero, the quadratic equation has two distinct real solutions. If the discriminant is equal to zero, the quadratic equation has one real solution. If the discriminant is less than zero, the quadratic equation has two complex solutions ( conjugates of each other )

In this video, we do a couple of examples.
