(m+4n)(m-n)-6(m+2n)(m-3n),
计算(m+4n)(m-n)-6(m+2n)(m-3n)
(m+4n)(m-n)-6(m+2n)(m-3n),
(m+4n)(m-n)-6(m+2n)(m-3n)
[(m-n)^2*(m-n)^3]^2/(m-n)^4
(m-n)2(n-m)3(n-m)4化简
[(m+n)(m-n)-(m-n)²+2n(m-n)]÷4n
初一计算:(m+5n)(m-n)-6(m+2n)(n-3n)?
(3m-4n)(4n+3m)-(2m-n)(2m+n)
[2(m+n)^5-3(m+n)^4+(-m-n)^3]÷[2(m+n)^3]
(m-5n)(m-n)-6(m+2n)(m-3n)
因式分解4m^2(m-n)+4n(n-m)
计算(m+n)^3-(n+m)(m-n)^2
