It can tell you three things about the quadratic equation:- 1. That the equation has 2 equal roots when the discriminant is equal to zero. 2. That the equation has 2 distinctive roots when the discriminant is greater than zero. £. That the equation has no real roots when the discriminant is less than zero.

That its roots (solutions) are coincident.

If the discriminant of a quadratic equation is less than zero then it has no solutions.

It has 2 equal solutions

It will then have 2 different roots If the discriminant is zero than it will have have 2 equal roots
