%28x%2B3%29%5E2=49 Start with the given equation.


x%2B3=0%2B-sqrt%2849%29 Take the square root of both sides.


x%2B3=sqrt%2849%29 or x%2B3=-sqrt%2849%29 Break up the "plus/minus" to form two equations.


x%2B3=7 or x%2B3=-7 Take the square root of 49 to get 7.


x=-3%2B7 or x=-3-7 Subtract 3 from both sides.


x=4 or x=-10 Combine like terms.

Answer:


So the solutions are x=4 or x=-10.
