Using the discriminate to describe the solutions of a quadratic

The video tutorial explains how to find the discriminant of a quadratic equation. It begins by converting the equation into standard quadratic form, ensuring it equals zero. The discriminant is derived from the quadratic formula, specifically the part under the square root. The tutorial demonstrates calculating the discriminant and interpreting its value, which indicates the nature of the solutions. A negative discriminant leads to imaginary solutions, introducing the concept of complex numbers. The video concludes with a summary of the process.
