Quadratic Equation Solver
Solve quadratic equations (ax² + bx + c = 0) and find real or complex roots using the quadratic formula.
How to Use the Quadratic Equation Solver
- 1
Enter coefficient a
Input the coefficient of x² (must not be zero).
- 2
Enter coefficient b
Input the coefficient of x.
- 3
Enter coefficient c
Input the constant term.
- 4
View solutions
See both roots, the discriminant, and vertex of the parabola.
💡 Tips & Tricks
- •If a = 0, the equation is linear (not quadratic) — use standard algebra instead.
- •The vertex form y = a(x-h)² + k gives you the maximum or minimum point.
- •Factoring is faster than the formula when the roots are integers.
