1/(1-x)+1/(1+x)+2/(1+x*x)+4/(1+x*x*x*x)+8/(1-x*x*x*x*x*x*x*x)怎么做
(x^2 + 4x)(x^2 + 4x+8)+16
(x^2-4x)(x^2-4x+8)+16
x^2-8x+16分之x^2-4x
（x^2-4x）/x^2-8x+16
因式分解：(X+2)(X+4)(X+6)(X+8)+16
计算(x+/1x)(x^2+1/x^2)(x^4+1/x^4)(x^8+1/x^8)(x^16+1/x^16)(x^2-1)

(x+x^-1)(x^2+x^-2)(x^4+x^-4)(x^8+x^-8)(x^16+x^-16)(x^2-1)=?
(x^2-8x+16)/(4-x^2)/(16-x^2)/(4+4x+x^2)
x/x-2=x²-8x+16/x²²-4x+4
(x+1)(x^2+1)(x^4+1)(x^8+1)(x^16+1)(x-1)
x=1-x/2+x/4-x/8+x/16-x/32
