Question

plz ans me that what is this origin
​

Answer 1

Step-by-step explanation:

$\sqrt{2} {x}^{2} + 7x + 5 \sqrt{2} = 0 \\ \sqrt{2} {x}^{2} +5x + 2x + 5 \sqrt{2} = 0 \\ x( \sqrt{2}x +5) + \sqrt{2}( \sqrt{2}x + 5) = 0 \\ (x + \sqrt{2} )( \sqrt{2} x + 5) = 0 \\ x = - \sqrt{2} \: \: \: or \: \: \: x = \frac{ - 5}{ \sqrt{2} }$
