Tolong bantu dong kak cara + jawaban nya :v

2 (log 3)
= log 3²
= log 9

alog b = log b/log a

Maka

6log (x²-4x - 50)-6log(2x+6) = 6log 9

6log (x²-4x -50)/2x+6 = 6log 9
x² - 4x - 50 / 2x+6 = 9
x² - 4x - 50 = 18x + 54
x² - 22x - 104 = 0
(x-26)(x+4) = 0
x = 26 (Memenuhi)
x = -4 (Tidak Memenuhi)


HP = {26}
