$$=\underset{{x}\rightarrow\mathrm{0}} {\mathrm{lim}}\:\frac{\frac{−{e}^{{x}} }{\mathrm{2}−{e}^{{x}} }}{\mathrm{1}+\frac{\mathrm{1}}{{x}}} \\ $$$$=\underset{{x}\rightarrow\mathrm{0}} {\mathrm{lim}}\:\frac{−{xe}^{{x}} }{\left(\mathrm{2}−{e}^{{x}} \right)\left({x}+\mathrm{1}\right)} \\ $$$$=\mathrm{0} \\ $$
