m^2-n^2+3m-3n x^2-5x-6 m^2-n^2+3m-3n
(n-m)^3×(m-n)^2-(m-n)^5
因式分解(n-m)^3(m-n)^2-(m-n)^5
初一计算:(m+5n)(m-n)-6(m+2n)(n-3n)?
(m-5n)(m-n)-6(m+2n)(m-3n)
若不等式(m+n)x+(2m-3n)
设不等式(m+n)x+(2m-3n)
设不等式(m+n)x+(2m-3n)
已知单项式M,N满足3x(M-5x)=6x^2y^3+N,求M,N
[(m-n)^2*(m-n)^3]^2/(m-n)^4
计算:1.[(m+n)(n-m)-(m+n)^2+3m(m+n)]除以(-2M),其中m=-4,n=2 2.(x+y)(
(m-n)2(n-m)3(n-m)4化简
计算(m+n)^3-(n+m)(m-n)^2
