To solve the quadratic equation \(2x^2 - 14x = 0\) by factoring out the greatest common factor (GCF), we start by finding the GCF of the terms.

  1. Identify the GCF: The GCF of \(2x^2\) and \(14x\) is \(2x\).

  2. Factor out the GCF: \[ 2x(x - 7) = 0 \]

  3. Set each factor equal to zero:

    • \(2x = 0\)
    • \(x - 7 = 0\)
  4. Solve each equation:

    • From \(2x = 0\), we get: \[ x = 0 \]
    • From \(x - 7 = 0\), we get: \[ x = 7 \]
  5. Conclude the solutions: The smaller solution is \(x = 0\), and the larger solution is \(x = 7\).

So the final answers are:

  • The smaller solution is \(x = 0\).
  • The larger solution is \(x = 7\).
