Answer
Answer choice $H$
Work Step by Step
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 $H$
