1) (1-2х)(4х²+2х+1)=8(1-х²)(х+2) СРОЧНО ! ДАЮ 19 БАЛЛОВ! 2) х³-2х²-3х+6=0 хотя бы одно!

1) (1 - 2х) * (4х^2 + 2х + 1) = 8 * (1 - х^2) * (х + 2);x^2 + 2x + 1 - 8x^3 - 4x^2 - 2x - 8x - 16 + 8x^3 + 16x^2 = 0;16x^2 - 8x - 15 = 0;D = 64 + 960 = 1024;x1 = (8 - 32)/32;x2=(8 + 32)/32;х1 = -3/4;х2 = 5/4.2)х^3 - 2х^2 - 3х + 6 = 0;x^2 * (x - 2) - 3 * (x - 2) = 0;(x - 2) * (x^2 - 3) = 0;x - 2 = 0;x = 2;x^2 - 3 = 0;x^2 = 3;x1 = -√3;x2 = √3.
