Solution for ln(x-2)+ln(x+1)=0 equation: 


Simplifying
ln(x + -2) + ln(x + 1) = 0

Reorder the terms:
ln(-2 + x) + ln(x + 1) = 0
(-2 * ln + x * ln) + ln(x + 1) = 0
(-2ln + lnx) + ln(x + 1) = 0

Reorder the terms:
-2ln + lnx + ln(1 + x) = 0
-2ln + lnx + (1 * ln + x * ln) = 0
-2ln + lnx + (1ln + lnx) = 0
