log8(x²-1)-log(3x+9)=0
log8(x²-1)=log(3x+9)
Removing log from both sides we get,
x²-1=3x+9
x²-1-3x-9=0
x²-3x-10=0
x²-5x+2x-10=0
x(x-5)+2(x-5)=0
(x+2)(x-5)=0
x=-2 (or) x=5
log8(x²-1)=log(3x+9)
Removing log from both sides we get,
x²-1=3x+9
x²-1-3x-9=0
x²-3x-10=0
x²-5x+2x-10=0
x(x-5)+2(x-5)=0
(x+2)(x-5)=0
x=-2 (or) x=5
