To simplify this expression, we can distribute the terms inside the brackets:
m(3m-2n) - m(3n-2m)
= 3m^2 - 2mn - 3mn + 2m^2
Now, let's combine like terms:
= 3m^2 + 2m^2 - 2mn - 3mn
= 5m^2 - 5mn
Finally, multiply the result by n:
(5m^2 - 5mn)n
= 5m^2n - 5mn^2
Therefore, the simplified expression is 5m^2n - 5mn^2.
