Right now we have:$${\mathtt{x}}{\mathtt{\,\times\,}}{\mathtt{3}}{\mathtt{\,\times\,}}{{\mathtt{x}}}^{{\mathtt{2}}}{\mathtt{\,\small\textbf+\,}}{\mathtt{2}}$$
While we cannot solve for x, we can simplify it to $${\mathtt{3}}{\mathtt{\,\times\,}}{{\mathtt{x}}}^{{\mathtt{3}}}{\mathtt{\,\small\textbf+\,}}{\mathtt{2}}$$, because, $${\mathtt{x}}{\mathtt{\,\times\,}}{{\mathtt{x}}}^{{\mathtt{2}}} = {{\mathtt{x}}}^{{\mathtt{3}}}$$.
