Jawaban Dari 1. -8 (4x - 3) 2 (3x + 1) (2x - 5) 3. (4a - 8) (5a - 6) 4. -3 (4y + 7)+ 9 (2y - 8)

1. -8 (4x - 3)
= -32x + 24

2. (3x + 1) (2x - 5)
= 6x² - 15x + 2x - 5
= 6x² - 13x - 5

3. (4a - 8) (5a - 6)
= 20a² - 24a - 40a + 48
= 20a² - 64a + 48

4. -3 (4y + 7) + 9 (2y - 8)
= -12y - 21 + 18y - 72
= -12y + 18 y -21 -72
= 6y - 93
