x = (-b ± √(b² - 4ac)) / 2a. The discriminant (b² - 4ac) determines the nature of the roots: positive gives two real roots, zero gives one repeated real root, and negative gives two complex roots.
It solves any quadratic equation in the form ax^2 + bx + c = 0 instantly using the quadratic formula.
x = (-b +/- the square root of (b^2 - 4ac)) / 2a.
The discriminant (b^2 - 4ac) determines the nature of the roots: positive gives two real roots, zero gives one repeated real root, and negative gives two complex roots.
Yes, when the discriminant is negative, the solver returns two complex roots.
You need the coefficients a, b, and c from the equation ax^2 + bx + c = 0.
