题目不完整吧?因试分解o
计算:2x/(x-2)(x+1)÷(1-x/x+1)-x²+2x/x²-4?
(-x^4)^2-2(x^2)^3×x×x+(-3x)^3×x^5
[(x+6)/(x-6)][(x-4)/(x+4)]^2+[(x-6)/(x+6)][(x+9)/(x-9)]^2=2(x^2+36)/(x^2-36)

4x+2*(8-x)=36
X/(2-X) -(4-X的平方)/(X的平方-4X+4)
(x/x-2-x/x+2)/4x/x-2
当x取何整数值时,能使下式值为正整数.(x^4+x^2-2)/(x^3-x^2+x-1)×(x-1)/(x^3+2x^2+2x+4)×(-2)/(x^3-x-x^2+1)
X^2-2X-4=0 X(X-7)=5X-36
