Jawaban:
a. X1 = -6 & X2 = 2
b. X1 = -5 & X2 = 3
c. X1 = 2 & X2 = 3
Penjelasan dengan langkah-langkah:
a. x² + 4x - 12 = 0
(x + 6)(x - 2) = 0
x + 6 = 0 atau x - 2 = 0
x = -6 atau x = 2
b. x² + 2x - 15 = 0
(x + 5)(x - 3) = 0
x + 5 = 0 atau x - 3 = 0
x = -5 atau x = 3
c. x² - 5x + 6 = 0
(x - 2)(x - 3) = 0
x - 2 = 0 atau x - 3 = 0
x = 2 atau x = 3
