    We make one side zero

    subtract 3 from both sides

    7k^2-6k=0

    factor out k

    (k) (7k-6) = 0

    set each to zero

    k=0

    7k-6=0

    add 6 to both sides

    7k=6

    diivde by 7

    k=6/7

    k=0 or 6/7

    Subtract 3 to get:

    7k^2-6k=0

    Clearly, we can factor out a k to find that:

    k (7k-6) = 0

    If either k or 7k-6 is zero, the whole expression is zero, so our solutions are zero and 6/7.
