sqrt%28x%2B2%29%2B15=11 Start with the given equation


sqrt%28x%2B2%29=-4 Subtract 15 from both sides


x%2B2=16 Square both sides


x=14 Subtract 2 from both sides


So the possible solution is x=14. However, we need to verify it.


Check:


sqrt%28x%2B2%29%2B15=11 Start with the given equation


sqrt%2814%2B2%29%2B15=11 Plug in x=14


sqrt%2816%29%2B15=11 Add


4%2B15=11 Take the square root of 16 to get 4


19=11 Add


Since the equation 19=11 is NOT true, this means that x=14 is not a real solution.
