(3m-4n)(-3m-4n)
(3m-4n)(-3m-4n)
(3m-4n)(-3m-4n)
=(4n-3m)(4n+3m)
=16n^2-9m^2
-9m^2+16n^2
(3m-4n)(-3m-4n)=-(3m-4n)(3m+4n)=-(9m的平方-16n的平方
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
(m-n)2(n-m)3(n-m)4化简
(m+n)^4+m(m+n)^3+n(n-m)^3 因式分解错了错(m-n)^4+m(m+n)^3+n(n-m)^3 因式分解
已知3m=4n,则m/m+n+n/m-n-m^2/m^2-n^2=
(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]
分解因式:(m-n)^4+n(m-n)^3+m(n-m)^4
(m-n)^4+m(m-n)^3-n(n-m)^3 这个怎么因式分解?
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|=n-m,且|m|=4,|n|=3,则m+n=?
(m-n)(m^5+m^4n+m^3n^2+m²n^3+mn^4+n^5)
计算4(m+n)^2·(-m-n)^3-(m+n)(-m-n)^4+5(m+n)^5
计算 4(m+n)^2*(-m-n)^3-(m+n)(-m-n)^4+5(m+n)^5 请写出步骤...
