To solve the quadratic equation \((x - 4)^2 = 25\) using square roots, proceed as follows:
-
Take the square root of both sides: \[ x - 4 = \pm 5 \]
-
This gives us two equations to solve:
- \(x - 4 = 5\)
- \(x - 4 = -5\)
-
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: \[ {-1, 9} \]
