The quadratic formula can be used to generate all of the data that the the b 2 - 4ac = 0, 2 equal real roots, graph is tangent to the x-axis (intersects the b 2 - 4ac no real roots, because graph does not intersect the x- axis.
What is a discriminant? A discriminant is a value calculated from a quadratic equation. It use it to ' discriminate' between the roots (or solu.
