Answer 1

To solve the quadratic equation \(7x^2 = 56x\), we start by moving everything to one side to put it in standard form:

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

2. Factor out the GCF: \[ 7x(x - 8) = 0 \]

3. Set each factor equal to zero: \[ 7x = 0 \quad \text{and} \quad x - 8 = 0 \]

4. The solutions are: \[ x = 0 \quad \text{and} \quad x = 8 \]

Thus, the correct steps are captured in the following response:

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 \(x = 8\)

This matches the second option in your list:

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