To solve the quadratic equation \(7x^2 = 56x\), we can first move all the terms to one side to set the equation to zero.
-
Put the quadratic in standard form: \[ 7x^2 - 56x = 0 \]
-
Factor out the GCF (Greatest Common Factor): The GCF here is \(7x\): \[ 7x(x - 8) = 0 \]
-
Set each factor equal to zero: This gives us the equations: \[ 7x = 0 \quad \text{and} \quad x - 8 = 0 \]
-
The solutions are: From \(7x = 0\), we get: \[ x = 0 \] From \(x - 8 = 0\), we get: \[ x = 8 \]
Thus, the correct steps are shown in this 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 \(x = 8\)
Therefore, the correct option 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 \(x = 8\)
