This video looks comprehensively at the use and need for the discriminant in solving quadratics.
The discriminant is a way to find if there is one, two or zero crossing points on the x-axis. This is a way to find if there are solutions to a quadratic equation. Solutions, in Mathematics, are simply the number of times a function crossing the x-axis.
