-------------
discriminant > 0 --> 2 intercepts.

the discriminant is b^2 - 4ac.

that's the expression within the square root sign of the quadratic formula.

if the discriminant is 0, then you have 1 real solution.

if the discriminant is negative, then you have 2 complex solutions (not real).

if the discriminant is positive, then you have 2 real solutions.

if the discriminant is positive and a perfect square, then you have 2 real solutions that are rational.

here's a couple of references.
