Try filling all of them in and seeing whether they satisfy the equation.

You can do it algebraically, or you can plug in the numbers from the list.

Algebraically is better, but because you need to square the entire left side it might be cumbersome.

Correct, using 8 gives $\sqrt{0}+8 = 8$ and using 9: $\sqrt{1}+8 = 9$

alright, thanks :]

$\sqrt{x-8}=x-8 \implies x-8=(x-8)^2$ $(x-8)^2-(x-8)=(x-8)(x-8-1)=0$ 8 and 9
