(m+1)(m-1)(㎡-1)

(m+1)(㎡+m+1) (M/1):(M/0. (((m>=1) & (m 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 计算M-M^2/M^2-1*M-1/M除以(M-1/M+1)^2 m-1/m=-1 那么㎡+m=? m=-1时,-2㎡-【-4m+(-m)】=? 解方程 2m-m*m 1=2(m*m-2m)(m*m-2m) 已知m＞4,化简|m-4|+|7-2m|+|m×m-2m+1|-|m×m-2m-3| 化简（m-1)(m+1)(m-1) (m+1)(m-1)(㎡-1) 数学题(m-1)(m²+m+1) 计算 (m+1)(m²+m-1) m²（m+1)-(m+1) 因式分解 因式分解：m²（m+1)-(m+1) 因式分解m^2(m+1)-(m-1) m-1分之m²-m+1
