а)1+4х+6х²+4х³+х⁴
b)1-6х+12х²-8х³
Объяснение:
а) (1+х)⁴ = (1+х)²(1+х)² = (1+2х +х²)(1+2х+х²) = 1+2х+х²+х+4х²+2х³+х²+2х³+х⁴ = 1+4х+6х²+4х³+х⁴
b) (1-2х)³ = 1-6х+12х²-8х³
а)1+4х+6х²+4х³+х⁴
b)1-6х+12х²-8х³
Объяснение:
а) (1+х)⁴ = (1+х)²(1+х)² = (1+2х +х²)(1+2х+х²) = 1+2х+х²+х+4х²+2х³+х²+2х³+х⁴ = 1+4х+6х²+4х³+х⁴
b) (1-2х)³ = 1-6х+12х²-8х³
