|2x-1| = |x+3| tolong yg bisa jwb yaa!!!

Mapel : Matematika
Kelas : X SMA
Materi : Persamaan Mutlak

Pembahasan :
|2x - 1| = |x + 3|
(2x - 1)² = (x + 3)²
(2x - 1)² - (x + 3)² = 0
(3x + 2)(x - 4) = 0
x = -2/3
x = 4

Hp : {-2/3 , 4}

|2x - 1| = |x + 3|
(2x - 1)² - (x + 3)² = 0
(3x + 2)(x - 4) = 0
x = -2/3 atau x = 4

HP = {-2/3 , 4}

a² - b² = (a + b)(a - b)
