Answer choice $H$
The easiest way to do this problem is to substitute the answer choices. You must plug $6,1,-6,-1$ into the quadratic. If you plug in $6$, $6+2=\sqrt {72-6-2}$ $8 = 8$ $\boxed{6}$ is a solution. If you plug in $-1$ $-1+2=\sqrt {2+1-2}$ $1 = 1$ $\boxed{-1}$ is a solution The answer is $H$
