Assume you mean:
:
%286-SqRt%2820%29%29%2F2
:
Find the largest square which is a factor of 20, it's 4, rewrite it:
:
%286-SqRt%284%2A5%29%29%2F2
:
:
Extract the square root of 4 and you have:
:
%286+-+2%2ASqRt%285%29%29%2F2
:
:
Note that you can divide the 2 into 2 and into 6, leaving you with
:
3+-+SqRt%285%29
