I think you mean sqrt(5-x) instead of (sqrt(5)-x).
sqrt%285-x%29%2B2=x-1
sqrt%285-x%29=x-3
5-x=%28x-3%29%5E2
5-x=x%5E2-6x%2B9
x%5E2-5x%2B4=0
%28x-1%29%28x-4%29=0
Two solutions:
x-1=0
x=1
and
x-4=0
x=4
Verify the solution by using the original equation.
sqrt%285-1%29%2B2=1-1
sqrt%284%29%2B2=0
2%2B2=0
No, not a solution.
sqrt%285-4%29%2B2=4-1
sqrt%281%29%2B2=3
3=3
True, x=4 is a solution.
