Tolong di jawab ya terima kasih

1] -3 ( 2p + 1 )
= -6p - 3

2] ( 2x + 3 ) ( 3x - 5 )
= 2x ( 3x - 5 ) + 3 ( 3x - 5 )
= 6x² - 10x + 9x - 15
= 6x² - x - 25

3] ( 3a² + 5b² ) ( a² - 5b² )
= 3a² ( a² - 5b² ) + 5b² ( a² - 5b² )
= 3a^4 - 15a²b² + 5a²b² - 25b^4
= 3a^4 - 10a²b² - 25b^4

4] ( 4p - 5q )²
= ( 4p - 5q ) ( 4p - 5q )
= 4p ( 4p - 5q ) - 5q ( 4p - 5q )
= 16p² - 20pq - 20pq + 25q²
= 16p² - 40pq + 25q²

1. -6p-3
2. 6x2 -10x + 9x - 15 = 6x2 - x - 15
3. 3a4 - 15a2b2 + 5a2b2 - 25b4 = 3a4 - 10a2b2 - 25b4
4. 16p2 - 40pq + 25q2
