已知3m^2-5m-1=0,则6m^2-10m+2=
m-2m-3m+4m-5m-6m+7m.2004m=?
(m+3m+5m.+2013m)-(2m+4m+6m+.+2012m)=?
(m+3m+5m+...+2015m)-(2m+4m+6m+...+2014m)=
已知3m^2-5m-1=0,则6m^2-10m+2=
(1m+3m+5m+...+2009m)-(2m+4m+6m+...=2008m)
已知m²+2m+1=0,求m³+2m²+3m
(m+3m+5m+7m+.+2009m)-(2m-4m-6m-.-2008m)=?
已知m^2+m-1=0,则m^3+2m^2+2004=
已知m²-3m-1=0,则2m²-3m+m的-2次方=?
已知m²-5m-1=0,z则2m²-5m+1/m²=?
已知m²-5m=0,则2m²-5m+1/m²=
已知m^2+m-1=0,求代数式m^3+5m^2+3m-2012的值
