sqrt%28T%2B3%29-sqrt%28T-2%29=sqrt%287-T%29
First, square both sides.

%28T%2B3%29-2sqrt%28%28T%2B3%29%28T-2%29%29%2B%28T-2%29=7-T
%282T%2B1%29-2sqrt%28%28T%2B3%29%28T-2%29%29=-T%2B7
-2sqrt%28%28T%2B3%29%28T-2%29%29=-3T%2B6
Square both sides.
4%28T%2B3%29%28T-2%29=9T%5E2-36T%2B36
4%28T%5E2%2BT-6%29=9T%5E2-36T%2B36
4T%5E2%2B4T-24=9T%5E2-36T%2B36
5T%5E2-40T%2B60=0
T%5E2-8T%2B12=0
%28T-2%29%28T-6%29=0
First solution
T-2=0
T=2
Second solution
T-6=0
T=6
