Answer
Multiply:$ - 3m^2n + 5mn - 4mn^2 and 6m^2n$
$= 6m^2n (- 3m^2n + 5mn - 4mn^2 )$
$= 6m^2n \times (- 3m^2n) + 6m^2n \times 5mn + 6m^2n \times (- 4mn^2)$
$= 18m^4n^2 + 30m^3n^2 - 24 m^3n^3$
$= 6m^2n (- 3m^2n + 5mn - 4mn^2 )$
$= 6m^2n \times (- 3m^2n) + 6m^2n \times 5mn + 6m^2n \times (- 4mn^2)$
$= 18m^4n^2 + 30m^3n^2 - 24 m^3n^3$
