计算x^3m/(x^m-1)-x^2m/(x^m+1)-1/(x^m-1)+1(x^m+1)

计算x^3m/(x^m-1)-x^2m/(x^m+1)-1/(x^m-1)+1(x^m+1) 计算 -(X^3)^M 计算：（1)x*x^m-1+x^2*x^m-2-3*x^3*x^m-3 计算:(1).(2x-3y)/(y-x)-(x+2y)/(x-y) (2).[5m/(m-3)+2m/(m+3)]*(m^2-9)/m 计算:x^m-1×x^3×(-x)^2×x^m= 计算(x+2)^m-1*(2+x)^m+1-(x+2)^2*(2+x)^2m 计算：x的平方+2（m-1)x+m的平方-2m-3=0 m(x+3m)²怎么计算 计算 (x+2)²-(x-1)(x+2) （m-2n+3)（m+2n-3) 计算(x-y)^m(y-x)^2m+(y-x)^3m (8x^2m-3-6x^m+2-4x^m)/(-2x^m-3)等于多少这是个计算 计算:(x^m+n)^2·(-x^m-n)^3+x^3m-n`(-x^3)^m 计算：2/1-m-1/m-1.2x/x-y -y/y-x -y-2x/x-y.12/m²-9 -2/m-3 计算：(m-1/m^2+3m+2)-(6/m^2-m-2)通分：x-2/4x^2-4x,x-1/x^2-2x,1/x^3-3x^2+2x m x平方-2x-m+1 因式分解(m-1)x-(x^2-m) 计算x*x的m-1次方+x的2次方*x的m-2次方 计算：(y-x)^3(x-y)^m-(x-y)^m+2(y-x)
