Answer 1

To factor the quadratic equation \( 7x^2 = 56x \), we first need to put it in standard form and find the correct steps.

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

2. Factor out the GCF (Greatest Common Factor): The GCF here is \( 7x \), so we factor it out: \[ 7x(x - 8) = 0 \]

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

4. Solve for \( x \): For \( 7x = 0 \): \[ x = 0 \] For \( x - 8 = 0 \): \[ x = 8 \]

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

Based on these steps, the correct table of solutions 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 \( x = 8 \)

So, the correct response from your options is: "Put the quadratic in standard form 7x²−56x=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."
