(x-5)^2=16

Solving the Equation (x - 5)^2 = 16

This equation involves a squared term, which we can solve by using the square root property. Here's how:

1. Isolate the Squared Term

The squared term is already isolated on the left side of the equation: (x - 5)^2 = 16

2. Take the Square Root of Both Sides

Taking the square root of both sides gives us: √((x - 5)^2) = ±√16

This results in: x - 5 = ±4

3. Solve for x

We now have two separate equations to solve:

  • Equation 1: x - 5 = 4 Adding 5 to both sides, we get: x = 9

  • Equation 2: x - 5 = -4 Adding 5 to both sides, we get: x = 1

Solution

Therefore, the solutions to the equation (x - 5)^2 = 16 are x = 9 and x = 1.

Checking the Solutions

We can verify our solutions by plugging them back into the original equation:

  • For x = 9: (9 - 5)^2 = 4^2 = 16 (True)

  • For x = 1: (1 - 5)^2 = (-4)^2 = 16 (True)

This confirms that both solutions are valid.
