m^2+3m-2,求3m^3+7m^2-12m+2014m^2+3m-2,求3m^3+7m^2-12m+2014m^2+3m-2,求3m^3+7m^2-12m+2014m²+3m=2原式=3
m^2+3m-2,求3m^3+7m^2-12m+2014
m^2+3m-2,求3m^3+7m^2-12m+2014
m^2+3m-2,求3m^3+7m^2-12m+2014
m²+3m=2
原式=3m³+9m²-2m²-6m-6m+2014
=3m(m²+3m)-2(m²+3m)-6m+2014
=6m-4-6m+2014
=2010
m-2m-3m+4m-5m-6m+7m-8m-9m+...+2002m-2003m-2004m求m的值
m-2m-3m+4m-5m-6m+7m.2004m=?
已知m＞4,化简|m-4|+|7-2m|+|m×m-2m+1|-|m×m-2m-3|
计算(m+3m+5m+7m+.+2009m)-(2m+4m+6m+.+2008m)
计算(m+3m+5m+7m+.+2013m)-(2m+4m+6m+.+2012m)
(m+3m+5m+7m+.+2009m)-(2m-4m-6m-.-2008m)=?
(m+3m+5m+7m+.+2011m)-(2m+4m+6m+.+2010m) 要说理由!
m^2+3m-2,求3m^3+7m^2-12m+2014
计算：m-2m-3m+4m-5m-6m+7m-8m-9m+...+2002m-2003m-2004m
m-2m-3m+4m-5m-6m+7m-8m-9m+.+2002m-2003m-2004m
计算：（m+3m+5m+...+2009m)-(2m+4m+6m+...+2008m)
(m+3m+5m+...+2009m)-(2m+4m+6m+...2008m)
(m+3m+5m+...+2014m)-(2m+4m+6m+...+2013m)
(m+3m+5m+...+2013m)-(2m+4m+6m+...+2012m)
(m+3m+5m+...+2015m)-(2m+4m+6m+...+2014m)=
计算:(m+3m+5m+...+2009m)-(2m+4m+6m+...+2010m)
(m+3m+5m.+2013m)-(2m+4m+6m+.+2012m)=?
计算m(m+7)-(m+3)(m-2).
