Solution for ln(X+3)+ln(X-1)=0 equation:


Simplifying
ln(X + 3) + ln(X + -1) = 0

Reorder the terms:
ln(3 + X) + ln(X + -1) = 0
(3 * ln + X * ln) + ln(X + -1) = 0
(3ln + lnX) + ln(X + -1) = 0

Reorder the terms:
3ln + lnX + ln(-1 + X) = 0
3ln + lnX + (-1 * ln + X * ln) = 0
3ln + lnX + (-1ln + lnX) = 0
