化简|2m+1|+|m-2|

已知m＞4,化简|m-4|+|7-2m|+|m×m-2m+1|-|m×m-2m-3| 化简|m|+|m-1|+|m-2| 化简:m+|(1+m^2-2m)/(m-1)| 化简 |m|+| (2+m-m^2) 除以(m+1) | 化简 |m|+| (2+m-m^2) 除以(m+1) | 化简|6-m|-|2m+1|+|m+5| (m M^2-2M+1/M^2-1除以(M-1-M-1/M+1)化简 化简m*m^2*m+m^2*m-m^2*m^2-m^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 化简(m*m-2m)/(4-m*m) m^2-m/m^2-1÷m/m-1乘（m+1/m-1)^2 化简 化简,:3(m-1)^2+(m+2)(m^2-2m+4)-m(m^2+3m-3) 已知m>4,化简:|m-4|+|7-2m|+|m^2-2m+1|-|m^2-2m-3| [2m-1]²+5m[m-1]-[3m+1][3m-1] 化简 3(m+1)平方-5(m+1)(m-1)+2m(m-1)化简,求值 化简：(m-1)+2(m²-3m)-(2-m+5m²) 化简：m(m-1)+(m的2次方-m)除以m+1
