Answer 1

Ответ:

1) -3а^3 - 9а^2 + 17

2) 2х^3 + 4х + 17

3) 3064 - 32b - 446^3

4) x^3 -22x - 23

Answer 2

1. (a³ - a² + 6) - (4a³ + 8a² - 11) = a³ - 4a³ - a² + 8a² + 6 + 11 = -3a³ + 7a² + 17

2. (11x + 21x³ - 43) + (60 - 19x³ - 7x) = 11x + 21x³ - 19x³ + 60 - 43 - 7x = 2x³ + 4x - 17

3. (3065 - 15b + 16) - (17 + 17b + 446³) = 3065 - 15b + 16 - 17 - 17b - 446³ = -446³ - 16 - 15b - 17b + 3065 - 17 = -446³ - 32 - 32b + 3048 = -446³ - 32b + 3016

4. (-73 + 17x + 19x³) + (-18x³ - 39x + 50) = -73 + 17x + 19x³ - 18x³ - 39x + 50 = x³ - 22x + -23
