Frequently Asked Questions
What types of equations can this solve? +
This tool solves three types: linear equations with one variable (like 3x + 5 = 20), quadratic equations (like x2 - 4x + 3 = 0), and systems of two linear equations with two variables (like x + y = 10 and 2x - y = 5).
How do I enter a quadratic equation? +
You can either enter the full equation (like 2x^2 + 5x - 3 = 0) or use the coefficient fields to enter the values of a, b, and c for the standard form ax2 + bx + c = 0.
Does it show the work for each step? +
Yes. Every solution includes a full step-by-step breakdown showing exactly how the answer was reached, including intermediate calculations like the discriminant for quadratic equations.
Can it handle complex or imaginary solutions? +
Yes. When a quadratic equation has a negative discriminant (no real roots), the solver will display the complex solutions using the imaginary unit i.
How do I enter a system of equations? +
Switch to the "System of Equations" tab and enter each equation on its own line. Use standard form like 2x + 3y = 7. The solver handles equations with x and y variables.
