Question

(2a + 1) (3a-2) (a-1)-(a + 2)³​

Answer 1

Ответ:

5a³-13a²-13a-6

Объяснение:

(2a + 1) (3a-2) (a-1)-(a + 2)³​
(6a²-4a+3a-2) (a-1) - (a+2)³​
(6a²-4a+3a-2) (a-1) - (a³​+6a²+12a+8)
(6a²-a-2) (a-1) - (a³+6a²+12a+8)
(6a²-a-2) (a-1) - a³-6a²-12a-8
6a³-6a²-a²+a-2a+2-a³-6a²-12a-8
5a³-6a²-a²+a-2a+2-6a²-12a-8
5a³-13a²+a-2a+2-12a-8
5a³-13a²-13a+2-8
ответ: 5a³-13a²-13a-6
