%28x%2B2%29%5E2=25 Start with the given equation.


x%2B2=%22%22%2B-sqrt%2825%29 Take the square root of both sides.


x%2B2=sqrt%2825%29 or x%2B2=-sqrt%2825%29 Break up the "plus/minus" to form two equations.


x%2B2=5 or x%2B2=-5 Take the square root of 25 to get 5.


x=-2%2B5 or x=-2-5 Subtract 2 from both sides.


x=3 or x=-7 Combine like terms.

Answer:


So the solutions are x=3 or x=-7.
