I'm not sure if that's a negative sign in front so here it is both ways:
a.
-%284m-3%29%2B%285m%5E2-4m%2B7%29
%28-4m%2B3%29%2B%285m%5E2-4m%2B7%29
%28-4m-4m%29%2B%285m%5E2%29%2B%283%2B7%29 Combine like terms
-8m%2B5m%5E2%2B10 Rewrite
5m%5E2-8m%2B10
b.
%284m-3%29%2B%285m%5E2-4m%2B7%29
%284m-4m%29%2B%285m%5E2%29%2B%28-3%2B7%29 Combine like terms
5m%5E2%2B4
