Answer 1

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

Answer 2

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

I hope that helps you
