设m^2 + m =1,求m^3 + 2m^2 +2005的值

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m²+m-1=0,求m^3+2m²+2009的值, 设m²+m-1=0,求m³+2m²+3的值 设m²+m=1,求m³+2m²+2009的值 设m²+m=1 求m³+2m²+2005的值 设m方加m=1,求m立方+2m方+2010的值 设m²+m-1=0,求m²+2m²+2008的值 设m²+m-1=0,求m³+2m²+2013的值 设m²+m-1=0,求m³+2m²+2013的值? 已知m*m+m-1=0,求m*m*m+2m*m-2005 设集合M=(1,2,3m-6),N=(-1,3),M交集N=(3),求m. 设m^2+2m+1=0,求m^3+2m^2+2008 的值 设m的平方+m-1=0,求m的三次方+2m²+3的值 设m^(2)+m-1=0.求m^(3)+2m^(2)+2004的值m^(2)+m-1=0,m^(2)+m=1m^(3)+2m^(2)+2004=m(m^(2)+m)+m^2+2004=m^(2)+m+2004=1+2004=2005这是书上的解释.我不明白m(m^(2)+m)+m^2和^(2)+m能和我解释下吗.
