tolong tuliskan soal aljabar beserta jawabanya 20 soal

1. 4 ( 7x + 5) = 28x + 20
2. -3 (5x - 2) = -15x + 6
3. 3 (2x + 4) = 6x + 12
4. - 4 (3x - 2) = -12x + 8
5. 2 (8x - 5) = 16x - 10
6. (2x + 5) (3x - 4) = 6x² - 8x + 15x - 20
= 6x² + 7x - 20
7. (3x - 6) (4x - 2) = 12x² - 6x - 24x + 12
= 12x² - 30x + 12
8. (3x + 2) ( x - 3) = 3x² - 9x + 2x - 6
= 3x² - 7x - 6
9. (2x - 4) (x + 9) = 2x + 18x - 4x - 36
= 2x + 14x - 36
10. (x + 3) (2x - 5) = 2x² - 5x + 6x - 15
= 2x² - x - 15
11. 6 (x - 4) = 6x - 24
12. 2 (2x + 5) = 4x + 20
13. 9 (3x - 1) = 27x - 9
14. 4 (x + 2) = 4x + 8
15. 1 (3x - 1) = 3x - 1
16. 4 (3a + 2) = 12a + 8
17. (x + 3) (x - 2) = x² - 2x + 3x - 6
= x² - x - 6
18. 2 (a - 8) = 2a - 16
19. (2x - 6) (3x + 5) = 6x + 10x - 18x - 30
= 6x - 8x - 30
20. (2x -1) (x + 2) = 2x² + 4x - x - 2
= 2x² + 3x - 2

semoga membantu ya ;)
