\left(x+9\right)^{2}-2+2=2
Add 2 to both sides of the equation.
\left(x+9\right)^{2}=2
Subtracting 2 from itself leaves 0.
x+9=\sqrt{2} x+9=-\sqrt{2}
Take the square root of both sides of the equation.
x+9-9=\sqrt{2}-9 x+9-9=-\sqrt{2}-9
Subtract 9 from both sides of the equation.
x=\sqrt{2}-9 x=-\sqrt{2}-9
Subtracting 9 from itself leaves 0.
