To solve the quadratic equation, we can start by simplifying the equation by expanding the square term:
$-9 + (x - 3)^2 - 4 = -4$
Simplifying further, we get:
$(x - 3)^2 - 13 = 0$
To solve for x, we can take the square root of both sides:
$\sqrt{(x - 3)^2 - 13} = \sqrt{0}$
Simplifying further, we have:
$x - 3 = \pm \sqrt{13}$
Adding 3 to both sides, we get:
$x = 3 \pm \sqrt{13}$
So the solutions to the quadratic equation are:
$x = 3 + \sqrt{13}$
$x = 3 - \sqrt{13}$
Therefore, the correct response is:
{8, -2}
