kak tolong dijawab ya please mohon bantuannya biar ku follow nanti ig kakak

Simak ya...

x² - 16 = 0
(x - 4)(x + 4) = 0
x = 4 atau x = -4

x² - 4x = 0
x(x - 4) = 0
x = 0 atau x = 4

x² - 6x + 8 = 0
(x - 2)(x - 4) = 0
x = 2 atau x = 4

x² + 7x - 18 = 0
(x - 9)(x + 2) = 0
x = 9 atau x = -2

x² - 5x - 14 = 0
(x - 7)(x + 2) = 0
x = 7 atau x = -2

2x² - 3x - 2 = 0
(2x + 1)(x - 2) = 0
x = -1/2 atau x = 2

3x² - 7x + 4 = 0
(3x - 4)(x - 1) = 0
x = 4/3 atau x = 1

6x² + 13x + 6 = 0
(3x + 2)(2x + 3) = 0
x = -2/3 atau x = -3/2

6x² - x - 12 = 0
(2x - 3)(3x + 4) = 0
x = 3/2 atau x = -4/3
