Factoring of $x^3-3x^2+30x-1$ I need help factoring 
\begin{align}
x^3-3x^2+30x-1=0.\tag{1}
\end{align}
Any thoughts? I've tried the old guess and check method with long division and $\left(x-\frac{1}{2}\right),\left(x-1\right),\left(x-12\right),\left(x-6\right)$, all to no avail.

Thank you for your time,
