penyelesaian nilai mutlak dari |x+½|=³/2

Bab Nilai Mutlak
Matematika SMA Kelas X

|x + 1/2| = 3/2
(x + 1/2)² = (3/2)²
(x + 1/2)² - (3/2)² = 0
(x + 1/2 + 3/2) (x + 1/2 - 3/2) = 0
(x + 2) (x - 1) = 0
x + 2 = 0 atau x - 1 = 0
x = - 2             x = 1

Pembahasan :
|x + 1/2| = 3/2

x + 1/2 = 3/2
x = 3/2 - 1/2
x = 2/2
x = 1

x + 1/2 = -3/2
x = -3/2 - 1/2
x = -4/2
x = -2
