( __х3+8____ - __8х3+1__) : (__8х3-1___ + ____х3-8____)
х3-2х2+4х 4х2-2х+1 4х2+2х+1 х3+2х2+4х
= ((х+2)(х²-2х+4) - (2х+1)(4х²-2х+1) ) ÷ ( (2х-1)(4х²+2х+1) + (х-2)(х²+2х+4)
х(х²-2х+4) (4х²-2х+1) (4х²+2х+1) х(х²+2х+4)
= х+2 - х(2х+1) × х = х+2-2х²-х × х = - (2х²-2)× х
х х(2х-1)+(х-2) х 2х²-х+х-2 х ×(2х²-2)
= - 1
