Whih of the following tables shows the correct steps to factor out the GCF and solve the quadratic equation 7x^2 =56x?

1 answer

To factor out the greatest common factor (GCF) and solve the quadratic equation \(7x^2 = 56x\), we start by rearranging the equation into standard form. This means we want to set the equation to zero:

  1. Rearrange the equation: \[ 7x^2 - 56x = 0 \]

  2. Identify the GCF of the terms on the left side. The GCF of \(7x^2\) and \(-56x\) is \(7x\).

  3. Factor out the GCF: \[ 7x(x - 8) = 0 \]

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

  5. Solve for \(x\):

    • From \(7x = 0\), we get \(x = 0\).
    • From \(x - 8 = 0\), we get \(x = 8\).

So, the solutions to the equation \(7x^2 = 56x\) are: \[ x = 0 \quad \text{and} \quad x = 8. \]

If you have multiple choice options or tables to choose from, look for a table that matches these steps: rearranging the equation, finding the GCF, factoring, and solving for \(x\).
