Answer 1

To solve the quadratic equation \(7x^2 = 56x\), we first rearrange it into 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. Solve for the solutions: \[ x = 0 \quad \text{and} \quad x = 8 \]

The correct response is the option that includes these steps, stating:

• 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 \(x = 8\)

In the provided options, the last option is correct. It repeats the steps correctly with:

• Standard form: \(7x^2 - 56x = 0\)
• GCF: \(7x(x - 8) = 0\)
• Setting factors equal: \(7x = 0\) and \(x - 8 = 0\)
• Solutions: \(x = 0\) and \(x = 8\)
