Well.... If you are thinking about factorization.... you can't...
But you can solve it
Re-meme-ber
$\pm a (\pm b \pm c) \pm d (\pm e \pm f) = (\pm a \times \pm b) \pm (a \times \pm c) \pm (d \times \pm e) \pm (d \times \pm f)$ $+-a(+-b+-c)+-d(+-e+-f)=(+-a xx+-b)+-(a xx+-c)+-(d xx+-e)+-(d xx+-f)$
So....
$- 3 (7 m - 6) + 5 (- 3 m - 3) = (- 3 \times 7 m) - (3 \times (- 6)) + (5 \times (- 3 m)) + (5 \times (- 3))$ $-3(7m-6)+5(-3m-3)=(-3xx7m)-(3 xx(-6))+(5xx(-3m))+(5xx(-3))$
Which is....
$- 21 m - (- 18) + (- 15 m) + (- 15)$ $-21m-(-18)+(-15m)+(-15)$
And...
$(-) \times (-) = (+)$ $(-)xx(-)=(+)$
$(+) \times (-) = (-)$ $(+)xx(-)=(-)$
Which gives us
$- 21 m + 18 - 15 m - 15$ $-21m+18-15m-15$
Regroup
$- 21 m - 15 m + 18 - 15$ $-21m-15m+18-15$
Solve
$- 36 m + 3$ $-36m+3$
