How to Use This Calculator
- Select the Equation Type that matches your problem β options range from Linear and Quadratic to Systems of 2 or 3 equations.
- Fill in the coefficients for your chosen type (e.g., a, b, c for a quadratic axΒ² + bx + c = 0).
- For systems of equations, enter each row's coefficients and the right-hand-side constant separately.
- The solver returns exact roots or solution sets; for quadratics, the discriminant tells you whether roots are real or complex.
- Use the Exponential and Logarithmic types when your equation involves e^x or log-base-a forms.
