log (x² -6)+log 2= 1 + log x saya butuh bantuan supaya saya bisa maju ke depan kelas nantinya

log (x²-6) + log 2 = 1 + log x
log (x²-6)2 = log10 + log x
log (2x²-12) = log 10x
2x²-12 = 10x
2x²-10x - 12 = 0
x²-5x - 6 = 0
(x-6)(x+1) = 0

x-6 = 0
x = 6
syarat x²-6 > 0 masukan x = 6
36-6 = 30 (positif)
jadi x = 3 memenuhi

x+1=0
x = -1
syarat x²-6 > 0 masukan x = -1
1-6 = -4 (negatif)
jadi x = -1 tidak memenuhi

HP = {6}
