1 answer

To solve the quadratic equation \((x - 4)^2 = 25\) using square roots, proceed as follows:

  1. Take the square root of both sides: \[ x - 4 = \pm 5 \]

  2. This gives us two equations to solve:

    • \(x - 4 = 5\)
    • \(x - 4 = -5\)
  3. Solve each equation:

    • For \(x - 4 = 5\): \[ x = 5 + 4 = 9 \]

    • For \(x - 4 = -5\): \[ x = -5 + 4 = -1 \]

Therefore, the solutions to the equation are \(x = 9\) and \(x = -1\).

The correct response is: \[ {-1, 9} \]
