(2m+3n)(2m-n)-4n(2m-n)因式分解(2m+3n)(2m-n)-4n(2m-n)因式分解(2m+3n)(2m-n)-4n(2m-n)因式分解(2m+3n)(2m-n)-4n(2m-n)
(2m+3n)(2m-n)-4n(2m-n)因式分解
(2m+3n)(2m-n)-4n(2m-n)因式分解
(2m+3n)(2m-n)-4n(2m-n)因式分解
(2m+3n)(2m-n)-4n(2m-n)
=(2m-n)(2m+3n-4n)
=2(2m-n)(m-2n)
[(m-n)^2*(m-n)^3]^2/(m-n)^4
[(m-n)^2*(m-n)^3]^2/(m-n)^4
4m(m-n)^2+4n(n-m)^3
(m-n)2(n-m)3(n-m)4化简
已知3m=4n,则m/m+n+n/m-n-m^2/m^2-n^2=
(1),(-m-n)(-m+n) (2),(-m+n)(m-n)
[(m+n)(m-n)-(m-n)²+2n(m-n)]÷4n
(m-2n)(-m-n)
(m-2n)(2n+m)-(-3m-4n)(4n-3m)=
(3m-4n)(4n+3m)-(2m-n)(2m+n)
[2(m+n)^5-3(m+n)^4+(-m-n)^3]÷[2(m+n)^3]
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),
(n/m+n/2m^2)*4m/n^2
4m^2(m+n)-9n^2(m+n)
因式分解4m^2(m-n)+4n(n-m)
3m(m-n)-2n(m-n)的平方
