+%28sqrt%283%29-5%29%2F%28sqrt%283%29%2B5%29+=%28-28%2B10sqrt%283%29%29%2F%2822%29
+%28sqrt%283%29-5%29%2F%28sqrt%283%29%2B5%29+=%28-14%2B5sqrt%283%29%29%2F%2811%29
The answer in the book is the same as this when you expand it.
%28-sqrt%283%29%2B5%29%5E2=3-10sqrt%283%29%2B25=28-10sqrt%283%29
So then,
