Solving the Equation (x - 8)(x - 8) = 0
This equation represents a simple quadratic equation in factored form. Here's how we can solve it:
Understanding the Concept
The equation (x - 8)(x - 8) = 0 states that the product of two factors is equal to zero. This means at least one of the factors must be equal to zero.
Solving for x
-
Set each factor equal to zero:
- (x - 8) = 0
- (x - 8) = 0
-
Solve for x in each equation:
- x = 8
- x = 8
The Solution
Therefore, the solution to the equation (x - 8)(x - 8) = 0 is x = 8. This is a double root, meaning the solution appears twice.
Visualizing the Solution
The equation (x - 8)(x - 8) = 0 represents a parabola that intersects the x-axis at a single point, x = 8. This is because the equation is a perfect square, and the parabola touches the x-axis at its vertex.
Conclusion
Solving the equation (x - 8)(x - 8) = 0 demonstrates a key principle of algebra: if the product of factors equals zero, at least one of the factors must equal zero. Understanding this principle is crucial for solving various types of equations.
