Equation Solver - Free Online Tool | PivaBox

Solve linear, quadratic, and systems of equations with step-by-step solutions and interactive parabola graphing

How to Use Equation Solver

1. Select the equation type: Linear (ax + b = c), Quadratic (ax + b = c = 0), or System of two linear equations
2. Fill in the coefficients (a, b, c) for your equation. For systems, provide coefficients for both equations
3. Click Solve to see the step-by-step solution. For quadratics, the discriminant analysis and a parabola graph with roots marked are shown automatically

Frequently Asked Questions

Is this equation solver free?

Yes, this equation solver is completely free. All calculations run locally in your browser.

What types of equations can I solve?

Linear equations (ax + b = c), quadratic equations (ax + b = c = 0) using the quadratic formula, and systems of two linear equations using Cramer rule.

How does the quadratic solver work?

It computes the discriminant. If > 0: two distinct real roots. If = 0: one real double root. If < 0: two complex conjugate roots. A parabola graph is drawn on Canvas.
