Question

please help me in this problem it's urgent​

Answer 1

Answer:

- 99/6

Step-by-step explanation:

p = 1/2

q = 1/3

(2p - 3q)(4p^2 + 12pq + 9q^2)

( 2 x 1/2 - 3 x 1/3)(4 x 1/2^2 + 12 + 1/2 + 1/3 + 9 x 1/3^2)

(2 - 3)(1 + 77/6 + 1)

-1(1 + 77/6 + 1)

-1 - 77/6 - 1

-2 - 77/6

= - 99/6

Answer 2

Answer:

8p³ +12p²q - 18pq² - 27q³ if p = 1/2, q = 1/3

Step-by-step explanation:

= 2p × (4p² + 12pq + 9q²) - 3q × (4p² + 12pq + 9q²)

= 8p³ + 24p²q + 18pq² - 3q × (4p² + 12pq + 9q²)

= 8p³ + 24p²q + 18pq² - 12p²q - 36pq² - 27q³

= 8p³ + 12p²q + 18pq² - 36pq² - 27q³

= 8p³ + 12p²q - 18pq² - 27q²
