Understanding Quadratic Roots: Analyzing the Discriminant

The video tutorial explains how to determine the nature of the roots of a quadratic equation by examining the discriminant. It covers the quadratic formula and how the discriminant, which is the part under the square root (b² - 4ac), indicates the number of solutions. A negative discriminant means no real solutions, zero means one solution, and a positive discriminant means two solutions. The tutorial includes practical examples to illustrate these concepts.

Explain the significance of a zero discriminant.

What are the possible outcomes when the discriminant is positive?
