I am trying to understand Laguerre's method for finding complex roots of polynomials. I don't know what the value of $n$ should be in the equation. I have seen some people say I should always set it to $2$, however, this hasn't worked for me.

$n$ is the degree of the polynomial you are trying to find the root of. It comes in because we assume there are $n$ roots, one close and the rest an equal distance away. See Wikipedia.
