(1 - x)⁴ = 1 - 4x + 6x² - 4x³ + x⁴
8 + 8х + 2х² = 2x² + 8x + 8 = x² + 4x + 4 = (x + 2)²
х² - 4 = (x - 2)(x + 2)
x³ - 8 = x³ - 2³ = (x - 2)(x² + 2x + 4)
-4 - 4х - х² = -x² - 4x - 4 = -(x² + 4x + 4) = -(x + 2)²
x³ + 8 = x³ + 2³ = (x + 2)(x² - 2x + 4)
4 - x² = (2 - x)(2 + x)
x² - 4x + 4 = (x - 2)²
4 - 4х + х² = (2 - x)²
X^2 - 3x / 8 = 0 | * 8
x^2 - 3x = 0
x(x - 3) = 0
x = 0 или x - 3 = 0, x = 3
Ответ: 0; 3
(х-4)*(х-2)= х²-6х+8
(3х+1)*(5у-6)= 15ху+5у-18х-6
(3у-2с)*(у+6с)= 3у²+16ус-12с²
