5x² - 3x² + 5x - 8 - 4 = 0
2x² + 5x - 12 = 0
(2x -3) (x + 4) = 0
x = 3/2 atau x = -4
b. x² + 3x - 40 = 0
(x + 8) (x - 5) = 0
x = -8 atau x = 5
c. x² - 15 = 2x
x² - 2x - 15 = 0
(x + 3) (x - 5) = 0
x = -3 atau x = 5
d. (x - 1)(x - 2) = 6
x² - 2x - x + 2 - 6 = 0
x² - 3x - 4 = 0
(x - 4) (x + 1) = 0
x = 4 atau x = -1
semoga membantu ya :)
