\textbf{Given:}

\mathsf{\sqrt{5}x^2+2x-3\sqrt{5}}

\textbf{To find:}

\textsf{Factors of}

\mathsf{\sqrt{5}x^2+2x-3\sqrt{5}}

\textbf{Solution:}

\textbf{Concept used:}

\boxed{\begin{minipage}{7cm}$\\\textsf{The method of wrriting the given polynomial}\\\\\textsf{into product of its factors is called Factorisation}\\$\end{minipage}}

\mathsf{Consider,}

\mathsf{\sqrt{5}x^2+2x-3\sqrt{5}}

\mathsf{=\sqrt{5}x^2+5x-3x-3\sqrt{5}}

\mathsf{=\sqrt{5}x(x+\sqrt{5})-3(x+\sqrt{5})}

\mathsf{=(\sqrt{5}x-3)\,(x+\sqrt{5})}

\implies\boxed{\mathsf{\sqrt{5}x^2+2x-3\sqrt{5}=(\sqrt{5}x-3)\,(x+\sqrt{5})}}
