    simplification

    I found this simplification, but I'm not understanding how they came up with mn - 3n

    simplify:
    2m^2n - 6mn
    ____________
    2m

    = 2m^2n - 6mn
    ______ ______
    2m 2m

    = mn - 3n

    2m 2m

    = mn - 3n
    \frac{2m^2n-6mn}{2m} = \frac{2m^2n}{2m}-\frac{6mn}{2m}

    = \frac{\color{red}2m\color{black}\times m \times n}{\color{red}2m}- \frac{\color{red}2m\color{black}\times 3 \times n}{\color{red}2m}

    = mn -3n
