$\huge\pink{ \boxed{ \bold{ \green{Solution :-}}}}$

Have Given :-

${( \sqrt{7} + \sqrt{2} )}^{2}$

Formula :-

$(a + b)^{2} = {a}^{2} + 2ab + {b}^{2}$

$\scriptsize{( \sqrt{7} + \sqrt{2} )}^{2} = {( \sqrt{7}) }^{2} + 2( \sqrt{7} )( \sqrt{2} ) + {( \sqrt{2} })^{2}$

$= 7 + 2 \sqrt{14} + 2$

$= 7 + 2 + 2 \sqrt{14}$

$= 9 + 2 \sqrt{14}$
