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.

What does it mean if the discriminant is zero?

Explain the implications of a negative discriminant in a quadratic equation.

How do you calculate the discriminant using the values of a, b, and c?
