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


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

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

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