What does it mean if the discriminant (b^2 - 4ac) is positive?

Back

If the discriminant is positive, the quadratic equation has two distinct real solutions.

What does it mean if the discriminant (b^2 - 4ac) is zero?

Back

If the discriminant is zero, the quadratic equation has exactly one real solution (a repeated root).
