\begin{gathered}\\ \sf\longmapsto x(4x+9x)=39\end{gathered}

\begin{gathered}\\ \sf\longmapsto x×13x=39\end{gathered}

\begin{gathered}\\ \sf\longmapsto 13x^{2}=39\end{gathered}

\begin{gathered}\\ \sf\longmapsto x^{2}=3\end{gathered}

\begin{gathered}\\ \sf\longmapsto x=±√3\end{gathered}

\begin{gathered}\\ \sf\longmapsto x=-√3\\x=√3\end{gathered}

\begin{gathered}\\ \sf\longmapsto   x_{1} =  -  \sqrt{3} , x_{2} =  \sqrt{3}\end{gathered}
