Here's the way lynx got the second answer

 

√2 - √6

______        multiply top/bottom by the conjugate of the denominator ⇒ √2 - √6

√2  + √6

 

 

√2 -√6     √2 - √6                 2 - 2√12 + 6          8  - 2*2√3

______    _____      =        ___________   =  __________    =

√2 + √6    √2 - √6                   2  -   6                     -4

 

8/-4   +     -4√3  / - 4

 

 

-2 +  √3
