pertanyaannya |5x-4|=6 tolong di jawab ya...!

nilai 1
5x - 4 = 6
5x = 6 + 4
5x = 10
x = 10 ÷ 5
x = 2

nilai 2
(5x - 4) kuadrat = 6 kuadrat
(5x - 4) . (5x - 4) = 36
25x kuadrat - 20x - 20x + 16 = 36
25x kuadrat - 40x = 20

25x kuadrat - 40x - 20 = 0
------------------------------------- ÷ 5

5x kuadrat - 8x - 4 = 0
(5x + 2) (x - 2) = 0

* 5x + 2 = 0
5x = - 2

* x - 2 = 0
x = 2

x = - 2/5

Semoga Membantu !
