Solve quadratic equations of the form: ax² + bx + c = 0

Overview

This tool solves equations of the form ax² + bx + c = 0.

You fill in three numbers: a, b, and c.

The calculator shows each step of the computation.

How to Use This Tool

Follow these clear steps:

Enter a value for coefficient a. This value must not be zero.
Enter a value for coefficient b. It controls the graph’s tilt.
Enter a value for coefficient c. It sets the starting point on the y-axis.
Press the “Calculate Roots” button to compute the solution.

Understanding the Output

The calculator displays the quadratic formula.

It shows how your numbers are substituted into the formula.

The tool computes the discriminant. This number tells you the type of roots.

If the discriminant is positive, you get two real roots.

If it is zero, you get one repeated root.

If it is negative, you get two complex roots.

The result also shows the vertex of the parabola, the axis of symmetry, and the y-intercept.

Limitations and Special Notes

You must use a nonzero value for coefficient a.

The calculator uses only the quadratic formula method.

Double-check your inputs before you calculate.

Common Use Cases
