设m^2+m=1,则m^3+2m^2+2007=?设m^2+m=1,则m^3+2m^2+2007=?设m^2+m=1,则m^3+2m^2+2007=?m^3+2m^2+2007=m(m^2+m)+m^

设m^2+m=1,则m^3+2m^2+2007=?
设m^2+m=1,则m^3+2m^2+2007=?

设m^2+m=1,则m^3+2m^2+2007=?
m^3+2m^2+2007 =m(m^2+m)+m^2+2007 =m*1+m^2+2007 =m+m^2+2007 =1+2007 =2008 所以m^3+2m^2+2007=2008

m^3+2m^2+2007 =m(m^2+m)+m^2+2007 =m+m^2+2007 =1+2007 =2008
