You can put this solution on YOUR website!
Even without solving, a sense that x-3 is 0 or 1.
sqrt%28x-3%29=x-3

x-3=%28x-3%29%5E2

x-3=x%5E2-6x%2B9

x%5E2-6x-x%2B9%2B3=0

x%5E2-7x%2B12=0

%28x-3%29%28x-4%29=0

Indicated solutions are 3 or 4.
Both are acceptable inputs for sqrt%28x-3%29.
These two input values for x also are in perfect agreement with the initial guess about x-3 and sqrt(x-3). You can use the found solutions to check this.
