ln(x+2)+ln(x-2)=4

Solution for ln(x+2)+ln(x-2)=4 equation:

Simplifying
ln(x + 2) + ln(x + -2) = 4

Reorder the terms:
ln(2 + x) + ln(x + -2) = 4
(2 * ln + x * ln) + ln(x + -2) = 4
(2ln + lnx) + ln(x + -2) = 4

Reorder the terms:
2ln + lnx + ln(-2 + x) = 4
2ln + lnx + (-2 * ln + x * ln) = 4
2ln + lnx + (-2ln + lnx) = 4

Reorder the terms:
2ln + -2ln + lnx + lnx = 4

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

Combine like terms: lnx + lnx = 2lnx
2lnx = 4

Solving
2lnx = 4

Solving for variable 'l'.

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

Divide each side by '2nx'.
l = 2n-1x-1

Simplifying
l = 2n-1x-1
