4m^4-4m^3+9m^2-12m+4=0怎么解
4m^4-4m^3+9m^2-12m+4=0怎么解

4m^4-4m^3+9m^2-12m+4=0怎么解
原式=(4m^4-4m^3+m^2)+(8m^2-4m)-8m+4
=m^2(2m-1)+4m(2m-1)-4(2m-1)
=(2m-1)(m^2+4m-4)
=0
所以2m-1=0或m^2+4m-4=0
m=1/2或m=-2+根号2或者m=-2-根号2

m-2m-3m+4m-5m-6m+7m-8m-9m+...+2002m-2003m-2004m求m的值计算：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-2m-3m+4m-5m-6m+7m.2004m=?
