Quadratic solver
Solve a quadratic with real or complex roots, or a degenerate linear equation.
Enter your values, then choose Calculate.
Limits
- Nonzero coefficient magnitudes must be from 1e-150 to 1e150. Results use double precision. Approximate real-number outputs use 12 significant digits unless a unit specifies otherwise.
- Desktop limits are provisional. Physical mobile and Safari verification remains open.
