+sqrt%28x%2B3%29=x-3
x%2B3=%28x-3%29%5E2
x%2B3=x%5E2-6x%2B9
x%5E2-7x%2B6=0
%28x-6%29%28x-1%29=0
Two solutions:
x-6=0
x=6
Checking the solution:
sqrt%286%2B3%29=6-3
sqrt%289%29=3
3=3
True
.
.
.
x-1=0
x=1
Checking the solution:
sqrt%281%2B3%29=1-3
sqrt%284%29=-2
2=-2
False
.
.
.
Only one solution, x=6
