    each has a common factor of \(k\) so you can "factor it out"

    It's not correct. When you take out the common factor k, what is left for each term?

    remember.. \[7k^2 = 7k \times k\]

    You cannot multiply the terms... One example: factor x^2 + 2x In this case, x is the common factor. Take it out and group the rest of the terms, that is x^2 + 2x = x (x) + 2(x) = x ( x+2) Can you try again for your question?
