We will have the following:
We are given the expression:
[tex]-(x+2)^2=-14[/tex]
Now, we eliminate both negative signs by dividing both sides by -1, that is:
[tex]\frac{-(x+2)^2}{-1}=\frac{-14}{-1}\Rightarrow(x+2)^2=14[/tex]
Now, we operate the square root, that is:
[tex]\sqrt{(x+2)^2}=\sqrt{14}\Rightarrow x+2=\sqrt{14}[/tex][tex]\Rightarrow x=\sqrt{14}-2[/tex]
