$${{\mathtt{x}}}^{{\mathtt{3}}}{\mathtt{\,-\,}}{\mathtt{12}}{\mathtt{\,\times\,}}{{\mathtt{x}}}^{{\mathtt{2}}}{\mathtt{\,-\,}}{\mathtt{177}}{\mathtt{\,\times\,}}{\mathtt{x}}{\mathtt{\,\small\textbf+\,}}{\mathtt{836}} = {\mathtt{0}} = \left\{ \begin{array}{l}{\mathtt{x}} = {\mathtt{4}}\\
{\mathtt{x}} = {\mathtt{19}}\\
{\mathtt{x}} = -{\mathtt{11}}\\
\end{array} \right\}$$
This obviously factors into (x-4)(x-19)(x+11)=0
