Which of the following tables shows the correct steps to factor out the GCF and solve the quadratic equation 7x ^ 2 = 56 * x' point ) 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 = 0an * dx + 8 = 0 The solutions are x = - 8an * dx = 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 7x ^ 2 - 56x = 0 Factor the GCF 7x(x - 8) = 0 Set each factor equal to zero 7x = 0an * dx - 8 = 0 The solutions are x = 0an * dx = 8 Put the quadratic in standard form 7x ^ 2 - 56x = 0 Factor out the GCF 7x(x - 8) = 0 Set each factor equal to 7x = 0 and x - 8 = 0 The solutions x = - 7 and x = 8
The correct table of steps to factor out the GCF and solve the quadratic equation 7x^2 - 56x = 0 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
