Quadratic equation solver

The following quadratic equation solver will solve a quadratic equation of the form: ax2 + bx + c = 0, where a, b, or c are all integers.

Enter the coefficients of the quadratic equation in the form ax² + bx + c = 0

To get started, just enter a, b, and c into the box.

Enter coefficient a into the first box on the left

Enter coefficient b into the box in the middle

Enter coefficient c into the box on the right.

Notice that if a = 0, the equation is not quadratic, but linear.

If b2 - 4ac < 0, you will i in the answers because the answers are complex numbers. Check this lesson to learn more about complex numbers.

Practice a lot and enjoy the calculator!
