$\frac{ \sqrt{5}- \sqrt{3} }{ \sqrt{5}+ \sqrt{3} } - \frac{ \sqrt{5}+ \sqrt{3} }{ \sqrt{5}- \sqrt{3} }= \frac{ (\sqrt{5}- \sqrt{3})^2- (\sqrt{5}+ \sqrt{3})^2 }{ (\sqrt{5}+ \sqrt{3})( \sqrt{5}- \sqrt{3} )}= \frac{5+3-2 \sqrt{15} -5-3-2 \sqrt{15} }{( \sqrt{5})^2-( \sqrt{3})^2 }= \frac{-4 \sqrt{15} }{2}=$ $=-2 \sqrt{15}$
