若(x+m)(x-5)=x^2-2x+3n,则m-n=正确结果是8,

若(x^2+3x)^2+(x^2+3x)-m=(x+4)(x-1)(x^2+3x+5),则常数m=________ (3x+1)(x-1)-（x+3)(5x-6)=-2x^2-11x+m,则m=? 已知（3x+1)(x-1)-(x+3)(5x-6)=x^2-10x+m,则m= 已知（3x+1)(x-1)-(x+3)(5x-6)=x^2-10x+m,则m= 若(x-m)(x-2)的积不含X,m=? (2x-3)(x-n)=2x^2+5x+m求m与n *-----------------------------------------------*| 6 4 X | 8 X X | X X 5 || X X X | X X X | X 7 8 || X X X | X X X | X X X ||---------------+---------------+--------------- || X X X | X X X | 5 1 X || X X X | X 6 X | X X X || 8 X X | 3 5 X | 2 X X || |x-2|-|x-m| 填九宫格帮帮忙.x x 6 x x 7 x x 98 x x x 3 x 1 x x 9 x x 6 x 5 x 3 x x x 3 x x x x 1 8x x x 9 x 1 x x x2 1 x x x x 6 x x x 6 x 7 x 3 x x 1 x x 9 x 2 x x x 47 x x 8 x x 5 x x 已知f(x)=m(x-2m)(x+m+3),g(x)=(2^x)-2,若∀x∈R,f(x) 若x^m=6,x^n=9,则(2x^3m*x^2n) / (x^m*x^n)^2*x^n 已知f(x)=m(x-2m)(x+m+3),g(x)=2^x-2,若同时满足条件:(1)对于任意实数x,f(x) 已知f(x)=m(x-2m)(x+m+3),g(x)=x-1,若同时满足条件：①对任意实数x,有f(x) 若（2x＋3）（x+m)=2x+5x-n,则m=?n=?若（2x＋3）（x+m)=2x+5x-n,则m=?n=? 若(x+m)(x-5)=x^2-2x+3n,则m-n=正确结果是8, 已知函数f(x)=x^2-2x+5 x属于【0,3】若m-fx>0有解求m 已知函数f(x)=x^2-2x+5 x属于【0,3】若m-fx>0有解求m 已知函数f(x)=x^2-2x+5 x属于【0,3】若m-fx>0有解求m
