### Basics

Below you can find a quadratic equation solver developed using a simple code in JavaScript. It uses the known formula to calculate the roots (real and complex) of a quadratic expression.

If you have

ax2 + bx + c = 0

you can solve for x using

### Example 2

If you have coefficients:

a = 1, b = 4 and c = 3

you'll get:

x1 = -1
x2 = -3
If you have coefficients:

a = 3, b = 4 and c = 5

you'll get:

x1 = -0.6667 + 1.1055i
x2 = -0.6667 - 1.1055i

### Online Calculator

 To be able to use the following calculator you have to allow the use of JavaScript codes on your navigator.

 Enter the three coefficients of your quadratic equation... a = b = c = The solutions are: x1 = x2 =
