化简,:3(m-1)^2+(m+2)(m^2-2m+4)-m(m^2+3m-3)
化简,:3(m-1)^2+(m+2)(m^2-2m+4)-m(m^2+3m-3)
化简,:3(m-1)^2+(m+2)(m^2-2m+4)-m(m^2+3m-3)
原式=3(m^2-2m+1)+(m^3+8)-(m^3+3m^2-3m)
=3m^2-6m+3+m^3+8-m^3-3m^2+3m
=11-3m
已知m＞4,化简|m-4|+|7-2m|+|m×m-2m+1|-|m×m-2m-3|
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|
(m^3-m)/(2m+2)化简
m(m-3)/2+m化简
化简|m|+|m-1|+|m-2|
[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+|(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(m+1)(m+2)(m+3)+1?
化简|m+2|+|m-3|
(1/m^2-3m)+(1/m^2-9m+18)+(1/m^2-15m+54)化简：(1/m^2-3m)+(1/m^2-9m+18)+(1/m^2-15m+54)
1/m(m+1)+1/(m+1)(m+2)+1/(m+2)(m+3)+.+1/(m+9)(m+10)
化简3(m+1)^2-5(m-1)(m+1)+2m(m-1),其中m=3
