Answer 1

HEY MATE HERE IS YOUR ANSWER--

$x = - \sqrt{2} \\ \\ putiing \: value \: of \: x \\ \\ 2 \sqrt{2} \times x \times x \times 5 \times x + \sqrt{2} \\ \\ 2 \sqrt{2} \times ( - \sqrt{2} ) \times ( - \sqrt{2} ) \times 5 \times( - \sqrt{2} ) + \sqrt{2} \\ \\ 2 \times ( - 2) \times( - \sqrt{2} ) \times ( - 5 \sqrt{2} ) + \sqrt{2} \\ \\ 4 \sqrt{2} \times 5 \sqrt{2} + \sqrt{2} \\ \\ 20 + \sqrt{2} \\ \\ value \: of \: \sqrt{2} = 1.41 \\ \\ 20 + 1.41 \\ \\ = > 21.41$
