1 answer

To solve the equation \( x^2 - 64 = 0 \), we can start by isolating \( x^2 \):

  1. Add 64 to both sides: \[ x^2 = 64 \]

  2. Now, we take the square root of both sides. Remember that taking the square root can yield both a positive and a negative solution: \[ x = \pm \sqrt{64} \]

  3. Since \( \sqrt{64} = 8 \), we have: \[ x = 8 \quad \text{or} \quad x = -8 \]

Thus, the solutions are: \[ x = 8, -8 \]

So, for Part 1, the correct choice is A. The solutions are: \[ x = 8, -8 \] You can write this as \( x = 8, -8 \) in your response box.
