*Polynomial equation* of n-th degree has the form:
a∙x
^{
n

b∙x
^{

c∙x
^{

d∙x +
e =
0

There are no formulas to find the roots of *polynomial equations* of n-th degree
(n ≥ 5) by its coefficients. It was for the first
time proved by the Norway mathematician Niels Abel.

However, the roots of the n-th degree polynomial can be found with any required accuracy by using the numerical methods. Our calculator uses the Laguerre numerical method.

To begin the calculations, the required accuracy and the maximum number of iterations to spend must be specified.
