The expression is:
%28sqrt%283%29+-+sqrt%28-36%29%29+%2A+%28sqrt%283%29+%2B+sqrt%28-36%29%29
We can use the identity %28a+-+b%29+%2A+%28a+%2B+b%29+=+%28a%5E2+-+b%5E2%29 which works for complex numbers too.
Hence
%28sqrt%283%29+-+sqrt%28-36%29%29+%2A+%28sqrt%283%29+%2B+sqrt%28-36%29%29
=
3+-+%28-36%29 = 3+%2B+36+=+39
