Frequently Asked Questions
How does the quadratic discriminant determine root types?
If Δ > 0, there are two distinct real roots. If Δ = 0, there is one real double root. If Δ < 0, there are two complex conjugate roots with imaginary unit i.
What is the standard quadratic formula?
x = (-b ± √(b² - 4ac)) / (2a).
