## Use
Open the calculator page and enter values. Query-string parameters can restore and bookmark a calculation.
Example: https://askcalculators.com/calculator/math-equation-solver/?equationType=linear&a=2&b=3&c=11

## Inputs
- equationType: Equation type; type=select; required; default=linear; values=linear|quadratic
- a: a; type=number; required; default=2
- b: b; type=number; required; default=3
- c: c; type=number; required; default=11

## Outputs
- solution: Solution; format=text; primary
- discriminant: Discriminant (quadratic); format=number
- verification: Verification; format=text

## Formula
linear x = (c − b) ÷ a; quadratic x = [−b ± √(b² − 4ac)] ÷ 2a

## Rules
- Empty optional inputs are undefined, not zero.
- Hidden conditional inputs are ignored.
- Do not invent missing required inputs.
