m^2-2m-1
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
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|
因式分解m^2(m+1)-(m-1)
m^2(m+1)-m-1 因式分解
化简|m|+|m-1|+|m-2|
分式m-m^2分之m^2-2m+1
化简:m+|(1+m^2-2m)/(m-1)|
(m+1)(m+2)(m-1)(m-2)怎么计算?
化简 |m|+| (2+m-m^2) 除以(m+1) |
化简 |m|+| (2+m-m^2) 除以(m+1) |
解不等式m(m^-2m+1)/m+1
m(m+1)(m+2)(m+3)+1?
化简|6-m|-|2m+1|+|m+5| (m
(1),(-m-n)(-m+n) (2),(-m+n)(m-n)
