Alg2/Trig E:
Calculate the discriminant of a quadratic equation. What does this number say about the roots of an equation without actually solving for them? If the discriminant is less than zero, we know the roots are imaginary; is a perfect square, they are rational; or is equal to zero, they are equal. What do the graphs of the quadratics convey about the nature of the roots?
