(3/2)^2-(2m-8)*3/2+m^2-16化简,
(3/2)^2-(2m-8)*3/2+m^2-16化简,我最需要的是过程.
4m^2-12m-7

(3/2)^2-(2m-8)*3/2+m^2-16
=9/4-3m+12+m^2-16
=m^2-3m-7/4

已知m＞4,化简|m-4|+|7-2m|+|m×m-2m+1|-|m×m-2m-3| (m^3-m)/(2m+2)化简 m-2m-3m+4m-5m-6m+7m-8m-9m+.+2002m-2003m-2004m (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+3-2m/m+3)÷m/m^-9
