help me plss bsk dikumpulkan​

Answer 1

Penjelasan dengan langkah-langkah:

[tex]1. \\ a(3a + 4b) = 3 {a}^{2} + 4ba[/tex]

[tex]2. \\ a(2a + 4b) = {2a}^{2} + 4ba[/tex]

3. 3(8a-4ab)=24a-12ab

4. 5(7a-2ab)=35a-10ab

5. -5(7a-2ab)=-35a+10ab

6. -5(-7a+2ab)=35a-10ab

7. -3a(7a+2ab)=-21a²-2a²b.

8. -3a(7a-2ab)=-21a+6a²b

9. -6a(8ab+4b)=-48a²b-24ba

10. -5a²(8b+2ab)=-40a²b-10a²b

11. -3a²(7ab-5b)=-21a²b+15ba²

12. -6a²(9ab+3a)=-54a²b-18a²

13. -3a(7a²-2ab)=-21a²+6a²b

14. -8a(7a²+5ab)=-56a²-40a²b

15. 9a²(7a-2b)=63a²-18b

16. 8a²(7ab+12b)=56a²b+96ba²

17. -6a²(9ab+3a)=-54a²b-18a²

18. -12a(4a²+3ab)=-48a²-36a²b

19. 6a(7a²-6ab)=42a²-36a²b

20. -9a²(7a-5b)=-63a²+45ba²
