Answer:
[tex]x+2=\pm2[/tex]
Step-by-step explanation:
He started with [tex](x+2)^2-9=-5[/tex].
He add 9 to both sides and the resulting equation was
[tex](x+2)^2=4[/tex]
Next, he took the square root of each side.
The resulting equation of this step is:
[tex](x+2)=\pm \sqrt{4}[/tex]
[tex]x+2=\pm2[/tex]
The required equation is:
[tex]x+2=\pm2[/tex]
