Equation Solver
Solve common equations quickly. This page supports linear equations of the form ax + b = c and quadratic equations of the form ax² + bx + c = 0.
Linear form: ax + b = c

How it works
This solver supports two common forms:
- Linear: ax + b = c → x = (c − b) / a
- Quadratic: ax² + bx + c = 0 → quadratic formula
For quadratics, the discriminant is D = b² − 4ac. If D is negative, there are no real-number roots.
Examples
- 2x + 3 = 7 → x = 2
- x² − 5x + 6 = 0 → x = 2, 3
- x² + 1 = 0 → no real roots

FAQ
- What equations does this solver support?
It supports linear equations of the form ax + b = c and quadratic equations of the form ax² + bx + c = 0.
- How does the linear solver work?
It rearranges ax + b = c into x = (c − b) / a, provided a is not 0.
- How does the quadratic solver work?
It uses the quadratic formula x = (-b ± sqrt(b² − 4ac)) / (2a).
- What if the quadratic discriminant is negative?
Then there are no real-number solutions. This page reports that the real roots do not exist.
- Are calculations stored?
No. Everything runs locally in your browser.
