Jawab:
9x² - 16 = 0
(3x + 4)(3x - 4) = 0
3x = -4 atau 3x = 4
x = -4/3 atau x = 4/3
--
x² + 6x + 8 = 0
(x + 4)(x + 2) = 0
x = -4 atau x = -2
--
x² + 3x - 18 = 0
(x + 6)(x - 3)=0
x = -6 atau x = 3
---
2x² + 13x + 15 = 0
(2x + 3)(x + 5) = 0
2x = -3 atau x = -5
x = -3/2 atau x = -5
--
3x² - 5x - 12 = 0
(3x + 4)(x - 3) = 0
3x = -4 atau x = 3
x = -4/3 atau x = 3
