IF x = $\frac{4 \sqrt{2}}{\sqrt{2} + 1}$ $(4sqrt(2))/{sqrt(2)+1}$ Then find $\frac{1}{\sqrt{2}} {(\frac{x + 2}{x - 2}) + (\frac{x + 2 \sqrt{2}}{x - 2 \sqrt{2}})}$ $1/sqrt(2){((x+2)/(x-2) ) +((x + 2sqrt(2))/(x - 2sqrt(2)))}$ ?

I am not sure if it is quite clear but here I go:

Anyway, please check my calculations.

IF x =4√2√2+1(4sqrt(2))/{sqrt(2)+1} Then find1√2{(x+2x−2)+(x+2√2x−2√2)} 1/sqrt(2){((x+2)/(x-2) ) +((x + 2sqrt(2))/(x - 2sqrt(2)))}?
