Question

Help me in this question please first
If x=[{(2)^1/2}+1]/[{(2)^1/2}-1] and y=[{(2)^1/2}-1]/[{(2)^1/2}+1] find the value of (x^2)+(y^2)+xy

Answer 1

I can't understand your question

plz translate in simple words

Answer 2

$x = \frac{ \sqrt{2} + 1 }{ \sqrt{2} - 1 }$

$y = \frac{ \sqrt{2} - 1 }{ \sqrt{2} + 1}$

${x}^{2} + {y}^{2} + xy$
