What expression in Microsoft Excel will ALWAYS correctly compute the following formula if the value of $x$ is in cell A$1?$

$\frac{5e^{-x}-5}{5!}$

$\frac{5^{**}\text{e}\text{x}\text{p}(-\text{\$}A\text{\$}1)-5}{f}$act$(5)$

$=\frac{5^{**}\text{e}\text{x}\text{p}(-\text{\$}A\text{\$}1)-5}{?}$ fact$(5)$

$=5^{**}$exp$(-A1)-\frac{5}{?}$ factorial$(5)$

$\frac{5^{**}{e}^{{?}^{{?}^{?}}}(-A1)-5}{5^{**}}{4}^{**}{3}^{**}{2}^{**}1$
