Answer 1

Hi there!!

Splliting the middle term method.

$2 {s}^{2} -(1 + 2 \sqrt{2} )s + \sqrt{2} \\ \\ = 2 {s}^{2} - s - 2 \sqrt{2} s + \sqrt{2} \\ \\ = s(2s - 1) - \sqrt{2} (2s - 1) \\ \\ = (2s - 1) \: and \: (s - \sqrt{2} ) \\ \\ = s = \frac{1}{2} and \: s = \sqrt{2}$

Hence, s = 1/2 and √2

Thankyou :)
