First we add this number :-

$= > 6m(m - 3) + 5m(3 - m) \\ = > 6 {m}^{2} - 18 + 15m - 5 {m}^{2} \\ = > 6 {m}^{2} - 5 {m}^{2} - 18 + 15 \\ = > {m}^{2} - 3$

Now we subtract this :-

$= > 9m(m - 12) - {m}^{2} - 3 \\ = > 9 {m}^{2} - 108 - {m}^{2} - 3 \\ = > 9 {m}^{2} - {m}^{2} -108 - 3 \\ → 8 {m}^{2} - 111$

Main Answer :-

$⇴8 {m}^{2} - 111$
