ln(X+1)+ln(X-1)=3

Solution for ln(X+1)+ln(X-1)=3 equation:

Simplifying
ln(X + 1) + ln(X + -1) = 3

Reorder the terms:
ln(1 + X) + ln(X + -1) = 3
(1 * ln + X * ln) + ln(X + -1) = 3
(1ln + lnX) + ln(X + -1) = 3

Reorder the terms:
1ln + lnX + ln(-1 + X) = 3
1ln + lnX + (-1 * ln + X * ln) = 3
1ln + lnX + (-1ln + lnX) = 3

Reorder the terms:
1ln + -1ln + lnX + lnX = 3

Combine like terms: 1ln + -1ln = 0
0 + lnX + lnX = 3
lnX + lnX = 3

Combine like terms: lnX + lnX = 2lnX
2lnX = 3

Solving
2lnX = 3
