数学m(m-n)^2+n(n-m)^2
数学m(m-n)^2+n(n-m)^2
m-n+2n^2/(m+n)
(m-n)^2 +n(n- m)
(m-n)+2n(m-n)
[(m+n)(m-n)-(m-n)²+2n(m-n)]÷4n
分式加减法:化简:2m/m-n-n/n-m+m+2n/n-m
计算m+2n/n-m+n/m-n-2m/n-m
计算2m-n/n-m+m/m-n+n/n-m
计算:2m-n/n-m+m/m-n+n/n-m
计算m+2m/n-m + n/m-n - 2m/n-m
问两个初二数学化简题:(1).(m+n)^×(n-m)^2×(m-n)+(n-m)^3×(n+m)^2×(m+n)^2
m/(m-n)^2-n/(n-m)^2
