What's A Discriminant?

We discussed what the discriminant is, and how it helps you determine how many solutions a quadratic equation will have. If the discriminant is positive, the equation will have two (2) solutions. If the discriminant is 0, then the equation will have one (1) solution. If the discriminant is negative, the equation will have no solutions. Solutions relate to the number of x-intercepts the parabola has.
