Solving the Equation (x-6)^2 = 9

This article will guide you through solving the equation (x-6)^2 = 9. We will explore the steps involved in finding the solutions for x.

Understanding the Equation

The equation (x-6)^2 = 9 represents a quadratic equation. It involves a squared term, which means we have two possible solutions for x.

Solving the Equation

  1. Take the square root of both sides: To get rid of the square, we take the square root of both sides of the equation. Remember that taking the square root introduces both positive and negative solutions.

    √(x-6)^2 = ±√9

  2. Simplify: Simplifying both sides gives us:

    x - 6 = ±3

  3. Isolate x: To find the values of x, we add 6 to both sides of the equation:

    x = 6 ± 3

  4. Calculate the solutions: This gives us two solutions:

    • x = 6 + 3 = 9
    • x = 6 - 3 = 3

Verifying the Solutions

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

  • For x = 9: (9 - 6)^2 = 3^2 = 9
  • For x = 3: (3 - 6)^2 = (-3)^2 = 9

Both solutions satisfy the original equation.

Conclusion

The solutions for the equation (x-6)^2 = 9 are x = 9 and x = 3. This demonstrates the process of solving quadratic equations with squared terms. By taking the square root of both sides and isolating x, we can find the two possible solutions.
