Quadratic Equation Solver

Introduction to Quadratic Equation Solver

The quadratic equation solver finds the real roots of a quadratic equation using the quadratic formula x = (-b ± sqrt(b^2 - 4ac)) / (2a). The input coefficients a, b, and c correspond to the coefficients in the quadratic equation ax^2 + bx + c = 0. The result is an array of real roots or an error message if the coefficients are invalid.

Parameter usage:

• a = coefficient of x^2 term
• b = coefficient of x term
• c = constant term

Output:

• Array of real roots or error message

Data validation

The coefficient a cannot be zero. The discriminant should be non-negative to have real roots.

Summary

This calculator finds the real roots of a quadratic equation given its coefficients.
