Question

Solve for x : √2 x2 + 7x + 5√2
​

Answer 1

Answer:

x= - √2 or  x= - 5/√2

Step-by-step explanation:

√2 x² +7x +5 √2 = 0

⇒ √2 x² + 5x + 2x + 5√2 = 0

 ⇒ √2x²  + 5x + √2*√2*x + 5√2=0

⇒ x(√2x + 5) + √2(√2x + 5) =0

⇒ (x+√2)(√2x+5) = 0

That gives x= - √2 or  x= - 5/√2

Answer 2

Step-by-step explanation:

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

$x = - \sqrt{2} \: andx = \frac{ - 5}{ \sqrt{2} }$

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

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

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