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
ax
^{2}
+
bx
+
c
= 0
you can solve for
x
using
Example 1
Example 2
If you have coefficients:
a = 1, b = 4 and c = 3
you'll get:
x
_{1}
= -1
x
_{2}
= -3
If you have coefficients:
a = 3, b = 4 and c = 5
you'll get:
x
_{1}
= -0.6667 + 1.1055i
x
_{2}
= -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:
x
_{1}
=
x
_{2}
=
