About the Quadratic Formula Calculator
This calculator solves quadratic equations of the form ax² + bx + c = 0. Enter the three coefficients and it returns both roots, whether they are real, repeated, or complex. You also get a detailed step-by-step solution that shows each calculation.
The tool applies the standard quadratic formula x = (-b ± √(b² - 4ac)) / (2a). You provide the coefficients a, b, and c from your equation. The calculator first computes the discriminant b² - 4ac to determine the type of roots, then substitutes your values into the formula. Check that a is not zero, because with a = 0 the equation is linear and the quadratic formula does not apply.
