m^3-m^2-2=0 求m的值.怎么算?

若m*m-3m+1=0,求分式2m*m+2\m*m的值, 已知m^2+m-0=0,求m^3+2m^2+2013的值 设m^2+m-1=0,求m^3+2m^2+2004的值 已知m^2+m-1=0求m^3+2m^2+2015的值 已知m^2+m-1=0,求m^3+2m^2+1997的值. 已知m^2+m-1=0,求m^3+2m-1997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 已知m^2+m-2=0 求m^3+2m^2-m+1的值 已知m^2+m-1=0,求m^3+2m^2+3m的值. 已知m^2-3m-1=0 求m^3-m^2-7m+2008的值 已知m^2+m-1=0,求代数式m^3+5m^2+3m-2012的值
