计算:12/m^2-9-2/m-3计算:12/m^2-9-2/m-3计算:12/m^2-9-2/m-3=12/(m+3)(m-3)-2/(m-3)=(12-2(m+3))/(m+3)(m-3)=(6-
计算:12/m^2-9-2/m-3
计算:12/m^2-9-2/m-3
计算:12/m^2-9-2/m-3
=12/(m+3)(m-3)-2/(m-3)
=(12-2(m+3))/(m+3)(m-3)
=(6-2m)/(m+3)(m-3)
=-2/(m+3)
计算:12/m^2-9-2/m-3
=(12-2(m+3))/(m+3)(m-3)
=(6-2m)/(m+3)(m-3)
=-2/(m+3)
12/m^2-9-2/m-3?应该是12/(m^2-9)-2/(m-3)吧?
如果是的话:
12/(m^2-9)-2/(m-3)
=12/[(m+3)(m-3)]-2/(m-3)
=12/[(m+3)(m-3)]-2(m+3)/[(m-3)(m+3)]
=[12-2(m+3)]/[(m+3)(m-3)]
=(12-2m-6)/[(m+3)(m-3)]
=2(3-m)/[(m+3)(m-3)]
=-2(m-3)/[(m+3)(m-3)]
=-2/(m+3)
计算(m^2-9)/[m(m-3)+m-3]
计算:m-2m-3m+4m-5m-6m+7m-8m-9m+...+2002m-2003m-2004m
计算:(m+3)( )=m^2-9

计算:(m+3m+5m+...+2009m)-(2m+4m+6m+...+2010m)
2m/m^2-9-1/m+3(计算)
计算:m-21/m^2-9 - 3/3-m另:
计算:12/m^2-9-2/m-3
计算:12/m²-9+2/3-m
12/m²-9减去2/m-3 计算,
计算 12/ m²-9 + 2/3-m
计算m(m+7)-(m+3)(m-2).
