(m+n)^2-4m(m+n)+4m^2 分解因式
thanks.

(m+n)^2-4m(m+n)+4m^2 分解因式thanks..
(m+n)^2-4m(m+n)+4m^2
=[(m+n)-2m]^2
=(n-m)^2
4m(m-m)-2n(n-m)
(n/m+n/2m^2)*4m/n^2
因式分解4m^2(m-n)+4n(n-m)
4m(m-n)^2+4n(n-m)^3
[(m-n)^2*(m-n)^3]^2/(m-n)^4
[(m-n)^2*(m-n)^3]^2/(m-n)^4
4m^2(m+n)-9n^2(m+n)
(m-n)2(n-m)3(n-m)4化简
[(m+n)(m-n)-(m-n)²+2n(m-n)]÷4n
(m-n)^2*(m-n)^4=?
化简,1.[(m+n-p)(m+p+n)-(m+n)²]/(-p),2.[(m+n)(m-n)-(m-n)²+2n(m-n)]/4n
已知3m=4n,则m/m+n+n/m-n-m^2/m^2-n^2=
m+n/4m^-n^-m-2m/n^-4m^=
(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]
(m+n)*(m-n)(m-2n)(m+2m)一定要过程!第4个是(m+2n)
计算(m+4n)(m-n)-6(m+2n)(m-3n)
