The discriminant is the part of the quadratic formula that is under the radical sign.

Quadratic formula:

So the discriminant is:

Use the discriminant to determine the character of the roots of a quadratic equation.

if there is one real number root with a multiplicity of 2.

if there are two real number roots.

if there is a conjugate pair of complex roots of the form
