Matematika SMA Kelas X

|2x - 1| = |4x - 3|

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

2x - 1 = - 4x + 3
2x + 4x = 3 + 1
6x = 4
x = 4/6
x = 2/3

HP = { 1, 2/3 }

Pembahasan :
|2x - 1| = |4x - 3|
(4x - 3)² = (2x - 1)²
(4x - 3)² - (2x - 1)² = 0
(4x - 3 + 2x - 1)(4x - 3 - 2x + 1) = 0
(6x - 4)(2x - 2) = 0
x = 2/3
x = 1

Hp : {2/3 , 1}
