Solving the Equation (x-2)^2 = 49

This article will guide you through the steps of solving the equation (x-2)^2 = 49.

Understanding the Equation

The equation involves a squared term, indicating a quadratic equation. To solve for 'x', we need to isolate it.

Step 1: Taking the Square Root

To get rid of the square, we take the square root of both sides of the equation:

√((x-2)²) = ±√49

This leads to two possible solutions:

  • x - 2 = 7
  • x - 2 = -7

Step 2: Isolating 'x'

Now, we need to isolate 'x' in both equations:

  • For x - 2 = 7, add 2 to both sides: x = 9
  • For x - 2 = -7, add 2 to both sides: x = -5

Solutions

Therefore, the solutions to the equation (x-2)² = 49 are x = 9 and x = -5.

Verification

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

  • For x = 9: (9-2)² = 7² = 49
  • For x = -5: (-5-2)² = (-7)² = 49

Both solutions satisfy the original equation.
