Answer 1

this is the answer .hope you enjoy

Answer 2

$hey \: mate \: here \: is \: your \: answer...$

${x}^{2} + \sqrt{2} x + k = 0$
$\: \: \: on \: putting \: x = \sqrt{2}$
$( \sqrt{2} ) {}^{2} + \sqrt{2} ( - \sqrt{2} ) + k = 0$
$2 - 2 + k = 0$
$k = 0$

$the \: value \: of \: k \: is \: 0$


$hope \: it \: helps....$
