The discriminant is part of the quadratic formula.

Quadratic Formula

#x=(-b+-sqrt(b^2-4ac))/(2a)#

Discriminant

#b^2-4ac#

The discriminant tells you the number and types of solutions to a quadratic equation.

#b^2-4ac = 0#, one real solution

#b^2-4ac > 0#, two real solutions

#b^2-4ac < 0#, two imaginary solutions
