2 / ( √2 x + [tex]\sqrt{2 x - 2 }[/tex] )
= [tex]2 ( \sqrt{2 x[/tex] + [tex]\sqrt{2x - 2 }[/tex] / ( [tex]\sqrt{2 x }[/tex] + [tex]\sqrt{2 x - 2 )[/tex] ( [tex]\sqrt{2 x }[/tex] - [tex]\sqrt{2 x - 2 ) }[/tex]
= [tex]2 \sqrt{2 x }[/tex] + [tex]2 \sqrt{2 x - 2 }[/tex] / [tex]2 x - 2 x - 2[/tex]
= [tex]\sqrt{2 x }[/tex] - [tex]\sqrt{2 x - 2 }[/tex]
