以知m^2+9n^2+6m+6n+10=0,求(m^2-6mn+9n^2)除以(m-3n)-(4m^2-9n^2)除以(2m-3n)的值

以知m^2+9n^2+6m+6n+10=0,求(m^2-6mn+9n^2)除以(m-3n)-(4m^2-9n^2)除以(2m-3n)的值 以知单项式M.N满足3X(M+6X^2)=18XY+N,求M和N (m+2n)-6(m+2n)(2m-n)+9(n-2m) 因式分解 因式分解：(2n-m)^2-6(2n-m)(m+n)+9(m+n)^2 m×m+n×n+2m-6n+10=0,m+n=?赶紧帮忙回答呀,谢谢谢 以知(m-x)*(-x)-(x+m)*(-n)=5x+x^2-6时,任意数都成立,求m(n-1)+n(m+1)的值? 求m,n 以知 3m－2n＝4 2m－3n＝6 (m+n)^2+6(m^2-n^2)=9(m-n)^2 满足m^2+n^2+2m-6n+10=0 m、n等于多少 若(m+n)^2-6(m+n)+9=1,则m+n=多少? （m+n)^2-6(m+n)+9=0,则m+n= 已知m^2+n^2-6m+10n+34=0,求m-n m^2+n^2-6m+10n+34=0,求m+n m^2+n^2-6m+10n+34=0求m+n的值 m²+2m+n²-6n+10=0 则m*n等于? m*+n*+2m-6n+10=0 ,求m+n? 6（m+n)²-2（m+n) 已知m^2+9n^2+6m+6n+10=0,求(m^2-6mn+9n^2)/(m-3n)-(4m^2-9n^2)/(2m-3n)
