Determine the number of solutions and tell if the discriminant is greater than 0, equal to 0 or less than 0.
When you have a quadratic equation in the form of ax%5E2%2Bbx%2Bc=0, the discriminant is b%5E2-4ac This is the inside part of the square root of the quadratic equation. If you keep this in mind, you'll remember that:
If the discriminant is greater than 0 there are two real solutions.
If the discriminant is equal to 0 there is one real solution.
If the discriminant is less than 0 there are two complex (or imaginary) solutions.
