Solving the Equation (x+8)(x+8) = 0
This equation represents a quadratic equation in its factored form. Let's break down how to solve for the value of 'x'.
Understanding the Equation
- Factored form: The equation is already factored. This means it's written as a product of two expressions: (x+8) and (x+8).
- Zero Product Property: The Zero Product Property states that if the product of two or more factors is zero, then at least one of the factors must be zero.
Solving for 'x'
- Apply the Zero Product Property: Since the product of (x+8) and (x+8) is zero, we know that at least one of these factors must be zero.
- Set each factor equal to zero:
- (x+8) = 0
- (x+8) = 0
- Solve for 'x' in each equation:
- x = -8
- x = -8
Solution
The solution to the equation (x+8)(x+8) = 0 is x = -8. This is a double root, meaning the solution appears twice.
Graphical Interpretation
The equation represents a parabola that touches the x-axis at the point (-8, 0). The fact that it's a double root means the parabola touches the x-axis but doesn't cross it.
