计算(5m+1)^2-(5m+1)(m-1)
3m-1)(m+1)+(2m-1)(m-1)-(3m+5)(m-2)怎么计算?
3(m+1)²-5(m+1)(m-1)+2(m-1)² 计算
1/(m^2-m)+(m-5)/(2m^2-2) 分式计算
计算 1/(m²-m)+(m-5)/(2m²-2)=?
化简|6-m|-|2m+1|+|m+5| (m
计算5-3分之m+2-7+m=1
计算:(m+3m+5m+...+2009m)-(2m+4m+6m+...+2010m)
(1m+3m+5m+...+2009m)-(2m+4m+6m+...=2008m)
计算 (m+1)(m²+m-1)
2m(m²-n+1)计算
(4m-5)(-5-4m)+(3m+1)(3m-1) 计算
问一道初一计算3(m+1)的平方-5(m-1)(m+1)+2m(m-1),先化简,再代入,m=3
