(3m-1)^2-4m(2m-1)=1我哪儿错了?.(3m-1)^2-4m(2m-1)=1,9m^2+1-6m-(8m^2+4m)=1,m^2-10m=1

已知m＞4,化简|m-4|+|7-2m|+|m×m-2m+1|-|m×m-2m-3| m*m-5m-1=0则2m*m-5m+1/m*m 已知m*m+m-1=0,求m*m*m+2m*m-2005 已知m-1/m=3,m不等于0,求m^2-1/m^2,m^3-1/m^3,m^4-1/m^4 当m=1/2时,求15m²-9-{-4m²+[5m-8m²-(2m²-m)+9m²]-3m} 已知m+1/m=3,计算(m^4+m^2+1)/m^2的值 若m^2+m=1,则2m^4+2m^3+2m+2012 [(m-3)/(m+5)]^2+[(4-2m)/(m+5)]^2=1,求m 已知m^2+m-1=0,那么m^4+2m^3-m-2009= m^2+m-6/m^2+2m+1÷m+3/m^+m·m^2-1/2-m 其中m=-1/2 化简求值m^2(m+4)+2m(m^2 -1)-3m^3,其中m=2/5 化简求值m^2(m+4)+2m(m^2 -1)-3m^3,其中m=2/5 解方程 2m-m*m 1=2(m*m-2m)(m*m-2m) 若m×(m+1)(m+2)(m+3)(m+4)共有40个不同的约数,则m= √(3m+1)(2-m)=√3m+1×√2-m成立时|m-4|√9m^2 6m+1+|m-2|化简 若m合适根号(3m+1)(2-m)=根号(3m+1)乘根号(2-m),化简|m-4|+|3m+1|+|m-2|. 化筒求值m^2(m+4)+2m(m^2-1)-3m(m^2+m-1),其中m=2/5.
