Solving the Quadratic Equation: (x-6)² - 5 = 0
This article will guide you through the steps of solving the quadratic equation (x-6)² - 5 = 0.
Understanding Quadratic Equations
A quadratic equation is an equation of the form ax² + bx + c = 0, where a, b, and c are constants and a ≠ 0. These equations can be solved using various methods, including factoring, completing the square, and the quadratic formula.
Solving the Equation
Let's solve the equation (x-6)² - 5 = 0 step by step:
-
Isolate the squared term: Add 5 to both sides of the equation: (x-6)² = 5
-
Take the square root of both sides: √(x-6)² = ±√5 Note that we introduce the ± sign since the square root of a number can be positive or negative.
-
Solve for x: x - 6 = ±√5 x = 6 ± √5
-
The solutions: Therefore, the solutions to the equation (x-6)² - 5 = 0 are:
- x = 6 + √5
- x = 6 - √5
Conclusion
By following these steps, we have successfully solved the quadratic equation (x-6)² - 5 = 0. The solutions are x = 6 + √5 and x = 6 - √5. This approach demonstrates how to utilize the properties of square roots and algebraic manipulation to find the roots of a quadratic equation.
