TEN5UKAN PERKALIAN AL JABAR BERIKUT! 2.-3pQ (7p+8pQ-5Q) 6.(3p+2Q) (p-5Q) 7.(3p-4Q) (2p+7Q) 8.4Q-3Q) (5p-4Q) 9.(a+3) (a+5) 10.(3a+a) (3a-2) 11.(2a-5) (2a-9)

2. -3pq (7p + 8pq - 5q)
= -21p^2q - 24p^2q^2 + 15pq^2

6. (3p + 2q) (p - 5q)
= 3p^2 - 15pq + 2pq - 10q^2
= 3p^2 - 13pq - 10q^2

7. (3p - 4q) (2p + 7q)
= 6p^2 + 21pq - 8pq - 28q^2
= 6p^2 + 13pq - 28q^2

8. (4q - 3q) (5p - 4q)
= q (5p - 4q)
= 5pq - 4q^2

9. (a + 3) (a + 5)
= a^2 + 5a + 3a + 15
= a^2 + 8a + 15

10. (3a + a) (3a - 2)
= (4a) (3a - 2)
= 12a^2 - 8a

11. (2a - 5) (2a - 9)
= 4a^2 - 18a - 10a + 45
= 4a^2 - 28a + 45
