%28x%2B3%29%5E2=5 Start with the given equation.


x%2B3=%22%22%2B-sqrt%285%29 Take the square root of both sides.


x%2B3=sqrt%285%29 or x%2B3=-sqrt%285%29 Break up the "plus/minus" to form two equations.


x=-3%2Bsqrt%285%29 or x=-3-sqrt%285%29 Subtract 3 from both sides.


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


Answer:


So the solutions are x=-3%2Bsqrt%285%29 or x=-3-sqrt%285%29.
