To solve the quadratic equation \( -9 + (x - 3)^2 - 4 = -4 \) using square roots, we will first simplify the equation.

  1. Start by simplifying the left side: \[ -9 + (x - 3)^2 - 4 = -4 \] Combine like terms: \[ (x - 3)^2 - 13 = -4 \] Add 13 to both sides: \[ (x - 3)^2 = 9 \]

  2. Now, take the square root of both sides: \[ x - 3 = \pm 3 \]

  3. Solve for \( x \):

    • For the positive case: \[ x - 3 = 3 \implies x = 6 \]
    • For the negative case: \[ x - 3 = -3 \implies x = 0 \]
  4. The solutions to the equation are \( x = 6 \) and \( x = 0 \).

The solution set is \({6, 0}\), which does not match any of the given response options exactly. Please check the choices provided or reconsider the question's context. If you meant to set up a different equation or you have a choice that reflects the values of \(x\) as needed, ensure the equation correlates correctly for future resolutions.
