Q:-solve the quadratic equation

$\sqrt{2} {x}^{2} + 7x + 5 \sqrt{2} = 0$

$\huge\tt\underline\blue{ANSWER }$

------>>>>Here is your answer<<<<--------

$⇛ \sqrt{2} {x}^{2} + 7x + 5 \sqrt{2} = 0$

$⇛ \sqrt{2} {x}^{2} + 2x + 5x + 5 \sqrt{2} = 0$

$⇛ \sqrt{2} x(x + \sqrt{2} ) + 5(x + \sqrt{2} ) = 0$

$⇛(x + \sqrt{2} )( \sqrt{2} x + 5)$

$⇛x + \sqrt{2} = 0$

$⇛x = - \sqrt{2} ✓$

$⇛ \sqrt{2} x + 5 = 0$

$⇛x = - \frac{5}{ \sqrt{2} } ✓$

HOPE IT HELPS YOU..
