4(2m+1)^2=9(2m-3)^2用分解因式求 速度啊啊啊啊啊啊啊啊

(m+3m+5m+...+2015m)-(2m+4m+6m+...+2014m)= m-2m-3m+4m-5m-6m+7m.2004m=? (m+3m+5m.+2013m)-(2m+4m+6m+.+2012m)=? 当m=1/2时,求15m²-9-{-4m²+[5m-8m²-(2m²-m)+9m²]-3m} m-2m-3m+4m-5m-6m+7m-8m-9m+...+2002m-2003m-2004m求m的值 已知m＞4,化简|m-4|+|7-2m|+|m×m-2m+1|-|m×m-2m-3| (m+3m+5m+7m+.+2009m)-(2m-4m-6m-.-2008m)=? √(3m+1)(2-m)=√3m+1×√2-m成立时|m-4|√9m^2 6m+1+|m-2|化简 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 m*m-5m-1=0则2m*m-5m+1/m*m 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) 计算:(m+3m+5m+...+2009m)-(2m+4m+6m+...+2010m) 已知m-1/m=3,m不等于0,求m^2-1/m^2,m^3-1/m^3,m^4-1/m^4 已知m*m+m-1=0,求m*m*m+2m*m-2005
