Quadratic Equation Solver

Solve any quadratic equation in seconds: enter coefficients a, b, and c, and instantly get both roots of x using the quadratic formula.

QUADRATIC FORMULA APPLIED AUTOMATICALLY

The app calculates x = (−b ± √(b² − 4ac)) / 2a, displays both results (x₁ and x₂), and evaluates the discriminant automatically. If the discriminant is negative, the app alerts you clearly: the equation has no real solutions. No manual steps, no calculation errors.

HOW TO USE IT

1. Enter the value of coefficient a (cannot be zero).

2. Enter the value of coefficient b.

3. Enter the value of coefficient c (constant term).

4. Tap Calculate and get x₁ and x₂ instantly.

ALSO KNOWN AS

A quadratic equation is also called a second-degree equation or a degree-2 polynomial equation: different names for the same problem, ax² + bx + c = 0, which this calculator solves directly.

FOR STUDENTS, TEACHERS, AND PROFESSIONALS

Perfect for students of all levels, from middle school to university, who are reviewing algebra or preparing for an exam: check your quadratic equation exercises on the spot and confirm your calculations are correct. Also useful for teachers preparing examples or reviewing student work quickly, and for professionals in physics, engineering, or economics who need to solve a quadratic equation as part of a larger calculation, such as a projectile's trajectory, an arch's design, or a cost optimization problem.
