Hasil dari |x²-4x-2| = x-8
|x² – 4x – 2| = x – 8
x² – 4x – 2 = x – 8
x² – 5 x + 6 = 0
(x – 3)(x – 2) = 0
x = 3 atau x = 2
-(x² – 4x – 2) = x – 8
x² – 4x – 2 = -(x – 8)
x² – 4x – 2 = -x + 8
x² – 3x – 10 = 0
(x – 5)(x + 2) = 0
x = 5 atau x = -2
Jadi, HP = {-2, 2, 3, 5}
|x²-4x-2| = x-8
x²-4x-x-2+8 = 0
x²-5x+6 = 0
(x-3)(x-2)=0
x = 2 atau x = 3
