|4x+2|=|6x-6| cara pengerjaannya bagai mana

|4x + 2| = |6x - 6|
(4x + 2)² - (6x - 6)² = 0
(10x - 4)(-2x + 8) = 0
x = 2/5 atau x = 4

HP = {2/5 , 4}

|4x + 2| = |6x - 6|

4x + 2 = 6x - 6
4x - 6x = -6 - 2
-2x = -8
x = -8/-2
x = 4

4x + 2 = -6x + 6
4x + 6x = 6 - 2
10x = 4
x = 4/10
x = 2/5

HP = {2/5, 4}
