To solve the quadratic equation \( 7x^2 = 56x \), we should first put it into standard form:

  1. Put the quadratic in standard form:
    \( 7x^2 - 56x = 0 \)

  2. Factor out the GCF (Greatest Common Factor):
    The GCF of \( 7x^2 \) and \( 56x \) is \( 7x \).
    Factoring it out gives:
    \( 7x(x - 8) = 0 \)

  3. Set each factor equal to zero:
    \( 7x = 0 \) and \( x - 8 = 0 \)

  4. The solutions are:
    From \( 7x = 0 \), we get \( x = 0 \).
    From \( x - 8 = 0 \), we get \( x = 8 \).

Thus, the solutions to the equation are \( x = 0 \) and \( x = 8 \).

The response that correctly shows 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 \( x=8 \)"**
