x^(3)*x^(2m +1)*x^(m)=x^(31) 求m的值

x^(3)*x^(2m +1)*x^(m)=x^(31) 求m的值 m x平方-2x-m+1 因式分解(m-1)x-(x^2-m) 计算x^3m/(x^m-1)-x^2m/(x^m+1)-1/(x^m-1)+1(x^m+1) 计算：（1)x*x^m-1+x^2*x^m-2-3*x^3*x^m-3 |x-2|-|x-m| (1-m)x^2+(m-3)x+2 十字相乘 2x-3m 7(m^3-m-1)-3(m^3+m) 2x^5(-x)^2-(-x^2)^3(-7x) (x+1)(x-1)(x^2+1) 解关于x的不等式:x^2-(3m+1)x+2m^2+m>0 分解因式x^m+3-2x^m+2y+x^m+1y^2 分解因式：x^m+3-2x^m+2*y+x^m+1*y^2 分解因式x^m+3-（2x^m+2）y+（x^m+1)y^2 x^2-（2m+1）x+m^2+m (x^2·x^m)^3/x^2m (x^2*x^m)^3/x^2m 韦达定理解：x^2+x>m(x-1)的解为｛x|x>3或x x^m×(x^n)^3÷[x^(m-1)×2x^(n-1)]=
