Faktorkan terlebih dahulu persamaan tersebut
|x + 2|² + 5|x + 2| - 6 = 0
(|x + 2| + 6)(|x + 2| - 1) = 0
|x + 2| + 6 = 0
|x + 2| = -6
(tidak ada x yang memenuhi karena bilangan mutlak tidak mungkin negatif)
|x + 2| - 1 = 0
|x + 2| = 1
x + 2 = 1
x = 1 - 2
x₁ = -1
x + 2 = -1
x = -1 - 2
x₂ = -3
p = -1
q = -3
p × q = -1 × -3 = 3
Penjelasan dengan langkah-langkah:
|x+2|² + 5|x+2| - 6 = 0
|x +2| - 1 = 0
|x +2| = -1
x1 = -1
x2 = -3
Q = -3
p x q
