Verified answer

Nomor 1
= 4a(2a - 5ab)
= 8a² - 20a²b

Nomor 2
= -2p(7p² + 4q)
= -14p³ - 8pq

Nomor 3
= pq(4p² - 3pq - 8q²)
= 4p³q - 3p²q² - 8pq³

Nomor 4
= -5a²(2a² + 8a²b - 5ab²)
= -10a⁴ - 40a⁴b + 25a³b²
= 25a³b² - 10a⁴ - 40a²b

Nomor 5
= (a + 4)(a + 5)
= a² + 5a + 4a + 20
= a² + 9a + 20

Nomor 6
= (6a - 5b)(4a + 9b)
= 24a² + 54ab - 20ab - 45b²
= 24a² + 34ab - 45b²
