Which of the following tables shows the correct steps to factor out the GCF and solve the quadratic equation 7x^2=56x

1 answer

To factor out the greatest common factor (GCF) and solve the quadratic equation \(7x^2 = 56x\), we can follow these steps:

  1. Set the equation to zero: We want all terms on one side of the equation. \[ 7x^2 - 56x = 0 \]

  2. Factor the left-hand side: Identify the GCF of the terms.

    • The GCF of \(7x^2\) and \(56x\) is \(7x\).
    • Factor out \(7x\): \[ 7x(x - 8) = 0 \]
  3. Use the Zero Product Property: Set each factor equal to zero.

    • \(7x = 0\) or \(x - 8 = 0\)
  4. Solve each equation:

    • From \(7x = 0\): \[ x = 0 \]
    • From \(x - 8 = 0\): \[ x = 8 \]
  5. Write down the final solution: The solutions to the equation \(7x^2 = 56x\) are: \[ x = 0 \quad \text{or} \quad x = 8 \]

In summary, to solve the quadratic equation \(7x^2 = 56x\), we factor out the GCF \(7x\), set each factor to zero, and solve to find the solutions \(x = 0\) and \(x = 8\).
