Frequently Asked Questions
What does the discriminant tell me?
Delta = b^2 - 4ac. Delta > 0: two real roots; Delta = 0: one repeated real root; Delta < 0: complex conjugate pair.
Why show decimal AND radical forms?
Decimal is convenient for follow-up calculations, but simplified radical form ((3 + sqrt(5))/2) is exact and often required in algebra classes.
How do I read the graph?
The vertex (-b/2a, c - b^2/4a) is marked amber; real roots green; y-intercept red — all key features at a glance.
