Question

solve the following quadratic equations by factorisation.
$\sqrt{} 2x { }^{2} + 7x + 5 \sqrt{2} = 0$
​

Answer 1

Answer:

$(\sqrt{2}x+5)(x+\sqrt{2} )$

Step-by-step explanation:

⇒$\sqrt{2}$x²+7x+5$\sqrt{2}$ = 0

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

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

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