Solution for ln(x)+ln(x-2)-ln(x+2)=0 equation: 


Simplifying
ln(x) + ln(x + -2) + -1ln(x + 2) = 0

Multiply ln * x
lnx + ln(x + -2) + -1ln(x + 2) = 0

Reorder the terms:
lnx + ln(-2 + x) + -1ln(x + 2) = 0
lnx + (-2 * ln + x * ln) + -1ln(x + 2) = 0
lnx + (-2ln + lnx) + -1ln(x + 2) = 0

Reorder the terms:
lnx + -2ln + lnx + -1ln(2 + x) = 0
lnx + -2ln + lnx + (2 * -1ln + x * -1ln) = 0
lnx + -2ln + lnx + (-2ln + -1lnx) = 0

Reorder the terms:
-2ln + -2ln + lnx + lnx + -1lnx = 0

Combine like terms: -2ln + -2ln = -4ln
-4ln + lnx + lnx + -1lnx = 0

Combine like terms: lnx + lnx = 2lnx
-4ln + 2lnx + -1lnx = 0

Combine like terms: 2lnx + -1lnx = 1lnx
-4ln + 1lnx = 0

Solving
-4ln + 1lnx = 0
