\textbf{Given:}

\mathsf{p^2+4p-16}

\textbf{To find:}

\textsf{Factors of}\;\mathsf{p^2+4p-16}

\textbf{Solution:}

\textsf{Consider,}

\mathsf{p^2+4p-16}

\textsf{This can be written as}

\mathsf{=(p^2+4p+4)-4-16}

\mathsf{=(p+2)^2-20}

\mathsf{=(p+2)^2-\sqrt{20}^2}

\mathsf{=(p+2-\sqrt{20})\;(p+2+\sqrt{20})}

\mathsf{=(p+2-2\sqrt{5})\;(p+2+2\sqrt{5})}

\implies\boxed{\mathsf{p^2+4p-16=(p+2-2\sqrt{5})\;(p+2+2\sqrt{5})}}

\textbf{Find more:}
