(m+n)(m-n)-(1-2n)化简
化简-3(m-n)²-(m-n)平方-3(m-n)+4m-n)的平方+2(m-n)-1
(1+n/m-n/m-n)÷(1-n/m-m/m+n) 化简,结果
化简1/6m-4n-1/6m+4n-3m/4n^2-9m^2
(m-n)2(n-m)3(n-m)4化简
(m-2n)^2+(3m-n)(2m+2n)-(2m+n)(2m-n) 已知m+n=4 mn=1

化简m-n-(m+n)1帮帮
-[2m-3(m-n+1)-2]-1化简
因式分解m^2-(n+1)m+n
m^2=n+2,n^2=m+2(m不等于n),求m^3-2mn+n^3的值因为m^2=n+2,n^2=m+2 所以 m^2-n^2=n-m 即 (m-n)(m+n)=n-m m+n=1为什么得m+n=1,求详解.
