How to use the discriminat to describe your solutions

The video tutorial explains the concept of the discriminant in quadratic equations, its role in determining the nature and number of solutions, and how it is used in conjunction with the quadratic formula. The tutorial provides a step-by-step calculation of the discriminant for a specific equation and interprets the results to identify the types of solutions possible.

What does the discriminant help us determine in a quadratic equation?
