Responses

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
Put the quadratic in standard form 7 x squared minus 56 x equals 0 Factor out the GCF 7 x left parenthesis x minus 8 right parenthesis equals 0 Set each factor equal to zero 7 x equals 0 and x minus 8 equals 0 The solutions are x equals 0 and x equals 8

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=−8 and x=0
Put the quadratic in standard form 7 x squared plus 56 x equals 0 Factor out the GCF 7 x left parenthesis x plus 8 right parenthesis equals 0 Set each factor equal to zero 7 x equals 0 and x plus 8 equals 0 The solutions are x equals negative 8 and x equals 0

Put the quadratic in standard form x−8=0
Factor out the GCF No GCF
Set each factor equal to zero x−8=0
The solutions are x=8
Put the quadratic in standard form x minus 8 equals 0 Factor out the GCF No GCF Set each factor equal to zero x minus 8 equals 0 The solutions are x equals 8

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=−7 and x=8

The correct steps to factor out the GCF and solve the quadratic equation \( 7x^2 = 56x \) are as follows:

  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: \( 7x = 0 \) and \( x - 8 = 0 \)
  4. The solutions are: \( x = 0 \) and \( x = 8 \)

Therefore, the first response in your list shows the correct solution. If you need to summarize it in one format:

  • 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 \( x = 8 \)
