Factoring and Solving (x-10)(x-10) = 0
The expression (x-10)(x-10) = 0 represents a quadratic equation in factored form. Here's a breakdown of how to factor, solve, and understand this equation:
Understanding the Factored Form
- (x-10)(x-10) = 0 means that we are multiplying two expressions together and the result is zero.
- 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
To solve for x, we apply the Zero Product Property:
-
Set each factor equal to zero:
- x - 10 = 0
- x - 10 = 0
-
Solve for x in each equation:
- x = 10
- x = 10
The Solution
We find that the equation has a double root at x = 10. This means the solution x = 10 occurs twice.
Graphing the Equation
The equation (x-10)(x-10) = 0 represents a parabola that touches the x-axis at the point (10, 0). The vertex of the parabola is also located at (10, 0).
Key Points
- Factored form makes solving quadratic equations easier by applying the Zero Product Property.
- A double root indicates that the solution occurs twice.
- The graph of a quadratic equation with a double root touches the x-axis at a single point, which is also the vertex of the parabola.
