Solution for ln(x^2-9)-ln(x+3)=2 equation: 


Simplifying
ln(x2 + -9) + -1ln(x + 3) = 2

Reorder the terms:
ln(-9 + x2) + -1ln(x + 3) = 2
(-9 * ln + x2 * ln) + -1ln(x + 3) = 2
(-9ln + lnx2) + -1ln(x + 3) = 2

Reorder the terms:
-9ln + lnx2 + -1ln(3 + x) = 2
-9ln + lnx2 + (3 * -1ln + x * -1ln) = 2
-9ln + lnx2 + (-3ln + -1lnx) = 2
