the discriminant is the part of the quadratic formula that is under the square root sign (b^2 - 4ac)

if the discriminant is a perfect square, the the roots are rational
___ if not a perfect square, the roots are irrational

if the discriminant is less than zero, the roots are imaginary
___ greater than or equal to zero, the roots are real

if the discriminant equals zero, the roots are equal
