3m-1)(m+1)+(2m-1)(m-1)-(3m+5)(m-2)怎么计算?
3m-1)(m+1)+(2m-1)(m-1)-(3m+5)(m-2)怎么计算?
计算2m+6/m²-4m+4·1/m+3·(m-2)(m+3)/m+3
(1m+3m+5m+...+2009m)-(2m+4m+6m+...=2008m)
已知m>4,化简|m-4|+|7-2m|+|m×m-2m+1|-|m×m-2m-3|
计算:(m-1/m^2+3m+2)-(6/m^2-m-2)
计算:(m+3m+5m+...+2009m)-(2m+4m+6m+...+2010m)
计算:-2m(m^2-1/2m+3)
3(m+1)²-5(m+1)(m-1)+2(m-1)² 计算
计算:(2m+1)(2m-1)-m·(3m-2) ;因式分解:n^2(m-2)+4(2-m)
化简2[(m-1)m+m(m+1)]乘【(m-1)m-m(m+1))
3(m+1)平方-5(m+1)(m-1)+2m(m-1)化简,求值
2m^2-5m+1/m^2 怎么等于(m^2-5M)+m^2+1/m^2
