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
m*m-5m-1=0则2m*m-5m+1/m*m
设m^2+m-1=0,则-m^3-2m^2+1=___
设m^2+m-1=0,则m^3+2m^2+99=?
设m^2+m=1,则m^3+2m^2+2007=?
设m^2+m=1,求m^3+2m^2+2009的值.
设m^2+m-1=0,求m^3+2m^2+2007的值
设m^2+m-1=0,求m^3+2m^2+2005的值
设m^2 + m =1,求m^3 + 2m^2 +2005的值
设m^2+m-1=0,求m^3+2m+2010的值
设m平方+m=1则m立方+2m平方+2007=?
设m²+m-1=0,则m³+2m²+1997=
设m²+m-1=0,求m^3+2m²+2009的值,
设m²+m-1=0,求m³+2m²+3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*m+m-1=0,求m*m*m+2m*m-2005
设m^2+m-1=0,则m^3=2m^2+99= 设m^2+m-1=0,则m^3=2m^2+99=
