Equation Solver

Three tools: linear solver, quadratic solver, and auto-detect mode.

Modify the values and click the Calculate button to use this tool.

Linear Equation

Solve ax + b = 0.

Modify the values and click the Calculate button to use this tool.

Quadratic Equation

Solve ax² + bx + c = 0.

Modify the values and click the Calculate button to use this tool.

Auto Detect

Leave c blank for linear.

Formula

Linear: x=−b/a | Quadratic: quadratic formula

How to use

  1. Pick the appropriate solver panel.
  2. Enter coefficients and calculate.

Formulas explained

Leave c empty in auto mode for linear; provide c for quadratic ax²+bx+c=0.

FAQ

If c is blank, solves ax+b=0; if c is provided, uses quadratic formula.
