Akar-akar persamaan x² + 2x - 8 = 0 adalah x1 = -4 dan x2 = 2
x1 . x2 = 3x1 . 4.x2
= 3(-4) . 4(2)
= -96
Pada persamaan x² + 10x - 16p = 0:
x1 . x2 = -16p
-16p = -96
<=> p = -96/-16
<=> p = 6
Jawaban: B
11)
x1 + x2 = 2x1 + 2x2
= 2(x1 + x2)
= 2(-8)
= -16
x1 . x2 = 2x1 . 2x2
= 4(x1.x2)
= 4(10)
= 40
Persamaannya adalah x² +16x + 40 = 0
Jawaban: B
