-4m-2m²=2 求m
-4m-2m²=2 求m
当m=1/2时,求15m²-9-{-4m²+[5m-8m²-(2m²-m)+9m
m-2m-3m+4m-5m-6m+7m.2004m=?
(m+3m+5m.+2013m)-(2m+4m+6m+.+2012m)=?
(m+3m+5m+...+2015m)-(2m+4m+6m+...+2014m)=
诺M²-2M=1,求2M²-4M+2010的值
已知m²+2m+1=0,求m³+2m²+3m
已知m²+m-4=0,求m四次方+2m三次方-m-2009
m²-4m+4/m²-1÷m-2/m+1+2/m-1,其中m=2
m³+2m²=m+m² m(m²+m)+m²拆开后应为m³+
(m+3m+5m+7m+.+2009m)-(2m-4m-6m-.-2008m)=?
化简求值(m+2/m²-2m)-(m-1/m²-4m+4)÷(m-1/m) 其中m=4
