kak tolong dong buat PAS ini

No. 24
( 4x + 2 ) ( x - 8)
= 4x² - 32x + 2x - 16
= 4x² - 30x - 16

No. 25
( 2x + 5 ) ( x + 2 )
= 2x² + 4x + 5x + 10
= 2x² + 9x + 10

No. 28
( 2x - 5y + 5 ) + ( 2x + y - 9)
= 2x + 2x - 5y + y + 5 - 9
= 4x - 4y - 4
= 4 ( x - y - 1 )

No. 29
( 7 ( y - 1 ) ) - ( 5 ( y - 1 ) )
= ( 7y - 7 ) - ( 5y - 5 )
= 7y - 5y - 7 + 5
= 2y - 2

No. 30
2p ( 4p - 3q )
= 8p² - 6pq
