原式===》m^2-2m^2+7m-60
(m-6)(m-1)>0
m6
(m-6)(m-1)>0
m6
已知m>4,化简|m-4|+|7-2m|+|m×m-2m+1|-|m×m-2m-3|
(m+3m+5m+.+2008m)-(2m+4m+6m+.+2009m)
(m+3m+5m+...+2009m)-(2m+4m+6m+...2008m)
m-2m-3m+4m-5m-6m+7m.2004m=?
计算:(m+3m+5m+...+2009m)-(2m+4m+6m+...+2010m)
(m+3m+5m+...+2013m)-(2m+4m+6m+...+2012m)
(m+3m+5m.+2013m)-(2m+4m+6m+.+2012m)=?
(m+3m+5m+...+2014m)-(2m+4m+6m+...+2013m)
(m+3m+5m+...+2015m)-(2m+4m+6m+...+2014m)=
化简(m*m-2m)/(4-m*m)
m+3m+5m+...+2011m-2m-4m-...-2010m等于多少?
(m+3m+5m+...+2009m)-(2m+4m+...+2008m)怎么算
