Solve quadratic equations. Input coefficients $a, b, c$ to compute discriminant and roots with step-by-step math formulas.
How to use
- Input the coefficients $a, b, c$ for the target quadratic equation.
- Check the discriminant $D = b^2 - 4ac$ output to inspect real vs complex root structures.
- Review the calculated roots and look at the step-by-step root-formula substitutions.
FAQ
- How are negative discriminants resolved?
- When the discriminant D is negative, the calculator computes complex roots using the imaginary unit $i$ (expressed as real part ± imaginary part * i).
