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

Solution for ln(x-1)+ln(x+1)=2 equation:

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

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

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

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

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

Combine like terms: lnx + lnx = 2lnx
2lnx = 2

Solving
2lnx = 2

Solving for variable 'l'.

Move all terms containing l to the left, all other terms to the right.
