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

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

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

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

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

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

Solving
4ln = 1

Solving for variable 'l'.

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