Underoot2x ^2 +7x +5 underoot2 =0
Plss do it and I will mark u

Answer 1

${ \bold{ \boxed{ \boxed{ \red { \bigstar \: ANSWER \: \bigstar}}}}}$

${ \bold{ \orange{ \implies \: \sqrt{2} {x}^{2} + 7x + 5 \sqrt{2} = 0 }}} \\ \\ { \bold{ \orange{ \implies \: \sqrt{2} {x}^{2} + 5x + 2x+ 5 \sqrt{2} = 0 }}} \\ \\ { \bold{ \orange{ \implies \:x( \sqrt{2} x + 5) + \sqrt{2} ( \sqrt{2} x + 5)= 0 }}} \\ \\ { \bold{ \orange{ \implies \:(x + \sqrt{2} )( \sqrt{2} x + 5) = 0}}} \\ \\ { \bold{ \orange{ \implies \boxed{\orange{ \:x = - \sqrt{2} \: , \: x = - \frac{5}{ \sqrt{2} } }}} }}$
