Simplify :

$( \sqrt{5} - \sqrt{2} ) {}^{2}$

$\color {red} </p><p>\Large \underline {\underline {Identity \: used\: :}}$

$(x - y) {}^{2} = {x}^{2} - 2xy + {y}^{2}$

$\color {red} </p><p>\Large \underline {\underline {Solution \: :}}$

$( \sqrt{5} - \sqrt{2} ) {}^{2}$

$= ( \sqrt{5} ) {}^{2} - 2( \sqrt{5} )( \sqrt{2}) + ( \sqrt{2} ) {}^{2}$

$= 5 - 2 \sqrt{10} + 2$

$= 7 - 2 \sqrt{10}$

$\implies$ Hence, the answer is 7 - 2√10.
