怎么求m^3-4m^2+m-6=0
怎么求m^3-4m^2+m-6=0

怎么求m^3-4m^2+m-6=0
m(m-2)^2-3m-6=0
(m-2)(m^2-2m-3)=0
(m-2)(m-3)(m+1)=0
m=2,3,-1

怎么求m^3-4m^2+m-6=0 m-2m-3m+4m-5m-6m+7m-8m-9m+...+2002m-2003m-2004m求m的值 (m+3m+5m+...+2015m)-(2m+4m+6m+...+2014m)= m-2m-3m+4m-5m-6m+7m.2004m=? (m+3m+5m.+2013m)-(2m+4m+6m+.+2012m)=? 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 (m+3m+5m+7m+.+2009m)-(2m-4m-6m-.-2008m)=? (m+3m+5m+...+2009m)-(2m+4m+...+2008m)怎么算 4m^4-4m^3+9m^2-12m+4=0怎么解计算(m+3m+5m……+2009m)—(2m+4m+6m+2008m)= 计算：（m+3m+5m+…+2015m）-(2m+4m+6m+…+2014m)= 计算（m+3m+5m+.+2009m)-(2m+4m+6m+.+2010m)=多少 (m+3m+5m+...+2011m)-(2m+4m+6m+...+2012m)=多少计算：(m+3m+5m+…+2011m)-(2m+4m+6m+…+2010m)= (m+3m+5m+...+2011m)-(2m+4m+6m+...+2012m)=多少计算(m+3m+5m+...+2011m)-(2m+4m+6m+...+2010m)= 计算：（m+3m+5m+...+2009m)-(2m+4m+6m+...+2008m)
