To solve the quadratic equation \(7x^2 = 56x\), you should first rearrange it into standard form, which is \(7x^2 - 56x = 0\).

Next, you factor out the greatest common factor (GCF), which is \(7x\). This gives us:

\[ 7x(x - 8) = 0. \]

Then, you set each factor equal to zero:

  1. \(7x = 0\) leads to \(x = 0\).
  2. \(x - 8 = 0\) leads to \(x = 8\).

Therefore, the solutions are \(x = 0\) and \(x = 8\).

The correct response based on these steps is:

Put the quadratic in standard form: \(7x^2 - 56x = 0\)
Factor out the GCF: \(7x(x - 8) = 0\)
Set each factor equal to zero: \(7x = 0\) and \(x - 8 = 0\)
The solutions are: \(x = 0\) and \(x = 8\)
