Answer:
Root5/root6+2×root6-2/root6-2
=root30-2root5/2...1
|||ly, root5/root6-2×root2+6/root6+2=root30+2root5/2...2
From 1and 2
Root30-2root5/2 -(Root30+2root5/2)
=root30-2root5-root30+2root5/2
(where root30 will get cancelled)
-2root5-2root5/2=-4root5/2
(where -4root5/2 can be reduced)
-2root5 is the answer.
