Equation Solver

Solve linear equations, systems of linear equations, and quadratic equations with detailed steps.

Solve ax + b = 0

Formulas

  • Linear: ax + b = 0 → x = -b/a
  • Linear System: Solved using Cramer's rule
  • Quadratic: x = (-b ± √(b²-4ac)) / 2a

Usage Instructions

Features

Online equation solver supporting linear equations, systems of linear equations, and quadratic equations, with automatic discriminant and detailed steps.

Steps

Select the equation type tab → enter coefficients → view real-time solution and steps; quadratic equations automatically compute the discriminant and identify real roots, repeated roots, or complex roots.

Notes

Coefficient a cannot be 0 for linear equations; a system has no unique solution when the determinant is 0; all calculations run locally in the browser.
