(x-2)²÷﹙2-x﹚的6次方=﹙x+3﹚﹙x-3﹚+1,
1/(x-2)^4=x^2-8,
(x^4-8x^3+24x^2-32x+16)(x^2-8)=1,
1..-8...24...-32.....16
..........-8.....64....-192...256...-128
..............................................-1
-------------------------------------------
1..-8....16...32...-176...256....-129|3
.....3....-15....3...105....-213....129
_____________________________
1...-5....1....35....-71.....43
x1=3,或x^5-5x^4+x^4+35x^2-71x+43=0,
还要继续求近似根吗?
