化简:3(m+1)+4(m+1)(m-1)-7m(m-1) 快
已知m>4,化简|m-4|+|7-2m|+|m×m-2m+1|-|m×m-2m-3|
已知m>4,化简:|m-4|+|7-2m|+|m^2-2m+1|-|m^2-2m-3|
化简2[(m-1)m+m(m+1)]乘【(m-1)m-m(m+1))
化简,:3(m-1)^2+(m+2)(m^2-2m+4)-m(m^2+3m-3)
(1m+3m+5m+...+2009m)-(2m+4m+6m+...=2008m)
化简:2{(m-1)m+m(m+1)}{(m-1)m-m(m+1)}.若m是任意整数.
化简:|m|+|m-1|+|m-2|.
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|.
