Question

A) (4-x)2xb)(x+y+xy^2)x^2 y

Answer 1

Не знаю вроде правильно мы такое не изучали я в 4

Answer 2

А)8х-2х²
б)х³у+х²у²+х³у³

Answer 3

a) Expanding the expression (4-x)2 gives:

(4-x)2 = (4-x)(4-x) = 4(4) - 4x - 4x + x2 = 16 - 8x + x2

Multiplying by 2 gives:

2(16 - 8x + x2) = 32 - 16x + 2x2

Therefore, (4-x)2 = 32 - 16x + 2x2

b) Expanding the expression (x+y+xy^2)x^2y gives:

(x+y+xy^2)x^2y = x^3y + x^2y^2 + x^3y^3

Therefore, (x+y+xy^2)x^2y = x^3y + x^2y^2 + x^3y^3.
