Solving the Equation: (x - 5)^2 = 36

This equation presents a simple quadratic equation in disguise. Let's break down how to solve it:

Understanding the Equation

The equation (x - 5)^2 = 36 represents the square of a binomial. To solve for x, we need to isolate it.

Solving for x

  1. Take the square root of both sides: √((x - 5)^2) = ±√36

  2. Simplify: x - 5 = ±6

  3. Isolate x: x = 5 ± 6

  4. Calculate the two possible solutions:

    • x = 5 + 6 = 11
    • x = 5 - 6 = -1

The Solutions

Therefore, the solutions to the equation (x - 5)^2 = 36 are x = 11 and x = -1.

Verification

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

  • For x = 11: (11 - 5)^2 = 6^2 = 36
  • For x = -1: (-1 - 5)^2 = (-6)^2 = 36

Both solutions satisfy the original equation, confirming their validity.

Conclusion

This example demonstrates how to solve a quadratic equation presented in a slightly different form. By utilizing basic algebraic operations and understanding the concept of square roots, we can arrive at the correct solutions.
