Answer 1

To solve the quadratic equation given by \( -9 + (x - 3)^2 - 4 = -4 \), we can start by simplifying the equation.

1. Clear the equation of constants:
\[
-9 + (x - 3)^2 - 4 = -4
\]
simplifies to:
\[
(x - 3)^2 - 13 = -4
\]
Adding 13 to both sides:
\[
(x - 3)^2 = 9
\]

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

3. Now, solve for \( x \):
- For the positive case:
\[
x - 3 = 3 \implies x = 6
\]
- For the negative case:
\[
x - 3 = -3 \implies x = 0
\]

Putting both solutions together, we have:
\[
\{6, 0\}
\]

However, this doesn't match any of your given options. It seems there may be a misunderstanding or error in transcribing the equation or options. Please double-check the equation or the potential answers provided.

If we revisit the simplification and computation steps, we can confirm that the solutions from the given equation should indeed yield \( x = 6 \) and \( x = 0 \). If the question or options are different, let me know for further clarification.
