Solving the Quadratic Equation: (x-2)(x-4) = 8
This article will guide you through the process of solving the quadratic equation (x-2)(x-4) = 8. We'll break down the steps and explore the different methods for finding the solutions.
1. Expanding the Equation
First, we need to expand the left side of the equation:
(x-2)(x-4) = 8 x² - 6x + 8 = 8
2. Simplifying the Equation
Next, we simplify the equation by subtracting 8 from both sides:
x² - 6x = 0
3. Factoring the Equation
Now we can factor out an x from the left side:
x(x-6) = 0
4. Solving for x
To find the solutions, we set each factor equal to zero:
x = 0 or x - 6 = 0
Solving for x in the second equation:
x = 6
Solutions
Therefore, the solutions to the equation (x-2)(x-4) = 8 are:
x = 0 and x = 6
Alternative Methods
While factoring is a straightforward method, there are other ways to solve quadratic equations:
- Quadratic Formula: This formula can be used to solve any quadratic equation in the form ax² + bx + c = 0.
- Completing the Square: This method involves manipulating the equation to create a perfect square trinomial.
You can choose the method that best suits your understanding and preference.
