Materi : Persamaan MutlakPembahasan :
|3x + 2| = 8
3x + 2 = 8 atau 3x + 2 = -8
3x = 8 - 2 atau 3x = -8 - 2
3x = 6 atau 3x = -10
x = 2 atau x = -10/3
Hp : {-10/3 , 2}
————————————————
|2x - 1| = |x + 3|
(2x - 1)² = (x + 3)²
(2x - 1)² - (x + 3)² = 0
(2x - 1 + x + 3)(2x - 1 - x - 3) = 0
(3x + 2)(x - 4) = 0
x = -2/3
x = 4
Hp : {-2/3 , 4}
