Solving the Equation (2x+4)(x-4) = 0

This equation is a quadratic equation in factored form, making it relatively straightforward to solve. Here's how we can approach it:

Understanding the Zero Product Property

The core principle we use is the Zero Product Property: if the product of two or more factors is zero, then at least one of the factors must be zero.

In our case, the factors are (2x + 4) and (x - 4). To make their product equal to zero, one or both of these factors must be zero.

Solving for x

  1. Set each factor equal to zero:

    • 2x + 4 = 0
    • x - 4 = 0
  2. Solve each equation for x:

    • 2x + 4 = 0

      • Subtract 4 from both sides: 2x = -4
      • Divide both sides by 2: x = -2
    • x - 4 = 0

      • Add 4 to both sides: x = 4

The Solutions

Therefore, the solutions to the equation (2x+4)(x-4) = 0 are x = -2 and x = 4.

These values of x make the equation true, as they make one or both of the factors equal to zero.
