Tentukan hasil pengurangan dari 5x (8y – 9z) dan 8y (5x – 5z)

5x( 8y – 9z )- 8y (5x – 5z)
(40xy -45 xz )-( 40yx – 40yz)
40xy-45 xz -40 xy + 40 yz
40 xy-40 xy -45 xz + 40 yz
-45xz + 40 yz

semoga membantu jadikan yg terbaik

5x ( 8y – 9z ) – 8y ( 5x – 5z )
= ( 5x × 8y) ( 5x – 9z ) – ( 8y × 5x ) ( 8y × -5z )
= 40xy – 45xz – 40xy -40yz
= 40xy – 40xy – 45xz – 40yz
= – 45xz – 40yz

Semoga membantu^^
