I'm going to assume the equation is sqrt%28x%2B6%29=0


sqrt%28x%2B6%29=0


%28sqrt%28x%2B6%29%29%5E2=0%5E2 Square both sides


x%2B6=0


x%2B6-6=0-6 Subtract 6 from both sides.


x=-6


So the possible solution is x=-6


------------------------------------------------------------------


Let's check the possible solution


sqrt%28x%2B6%29=0


sqrt%28-6%2B6%29=0 Plug in x = -6


sqrt%280%29=0


0=0 The equation is true, so the solution is confirmed.


------------------------------------------------------------------


So the solution is indeed x=-6
