They explain how the discriminant is contained within the quadratic formula and how it can be used to determine the number of roots or intersections between a quadratic curve and a straight line. The presenter goes through several examples, including finding the value of k for a tangent line to a curve, and demonstrates how to use the discriminant to solve for x-intercepts and turning points on a graph.\n
