(3x+2) (2x+1) (3x-2) (2x-1) (5x-2) (3x-4) tolong di jawab ya plis

1. (3x+2) (2x+1)
= 6x^2 + 3x + 4x + 2
= 6x^2 + 7x + 2

2. (3x-2)(2x-1)
= 6x^2 - 3x - 4x + 2
= 6x^2 - 7x + 2

3. (5x-2)(3x-4)
= 15x^2 - 20x - 6x + 8
= 15x^2 - 26x + 8

Semoga membantu :)

(3×2)=6 (2×1)=2
(3×-2)=-6 (2×-1)=-2
(5×-2)=-10 (3×-4)=-12
