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


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

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

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