Analyzing Quadratic Equations: Determining the Number of Real Solutions

This video tutorial explains how to determine the number of real solutions a quadratic equation has by examining the discriminant. It covers the quadratic formula, the role of the discriminant, and the three possible cases: positive, zero, and negative discriminants. Examples are provided to illustrate each case, showing how the discriminant affects the number of real roots and the graph of the quadratic function.
