Assuming x%3E=0


%28sqrt%28x%29-sqrt%285%29%29%5E2


%28sqrt%28x%29-sqrt%285%29%29%28sqrt%28x%29-sqrt%285%29%29


sqrt%28x%29%2A%28sqrt%28x%29-sqrt%285%29%29-sqrt%285%29%2A%28sqrt%28x%29-sqrt%285%29%29





sqrt%28x%2Ax%29-sqrt%28x%2A5%29-sqrt%285%2Ax%29%2Bsqrt%285%2A5%29


sqrt%28x%5E2%29-sqrt%285x%29-sqrt%285x%29%2Bsqrt%285%5E2%29


x-sqrt%285x%29-sqrt%285x%29%2B5


x-2%2Asqrt%285x%29%2B5


x%2B5-2%2Asqrt%285x%29


=======================================================


So %28sqrt%28x%29-sqrt%285%29%29%5E2 expands and simplifies to x%2B5-2%2Asqrt%285x%29 (where x%3E=0)
