Solution for ln(x+1)+ln(x-2)=ln(4) equation: 


Simplifying
ln(x + 1) + ln(x + -2) = ln(4)

Reorder the terms:
ln(1 + x) + ln(x + -2) = ln(4)
(1 * ln + x * ln) + ln(x + -2) = ln(4)
(1ln + lnx) + ln(x + -2) = ln(4)

Reorder the terms:
1ln + lnx + ln(-2 + x) = ln(4)
1ln + lnx + (-2 * ln + x * ln) = ln(4)
1ln + lnx + (-2ln + lnx) = ln(4)

Reorder the terms:
1ln + -2ln + lnx + lnx = ln(4)

Combine like terms: 1ln + -2ln = -1ln
-1ln + lnx + lnx = ln(4)

Combine like terms: lnx + lnx = 2lnx
-1ln + 2lnx = ln(4)

Reorder the terms for easier multiplication:
-1ln + 2lnx = 4ln

Solving
-1ln + 2lnx = 4ln

Solving for variable 'l'.

Move all terms containing l to the left, all other terms to the right.

Add '-4ln' to each side of the equation.
-1ln + -4ln + 2lnx = 4ln + -4ln

Combine like terms: -1ln + -4ln = -5ln
-5ln + 2lnx = 4ln + -4ln

Combine like terms: 4ln + -4ln = 0
-5ln + 2lnx = 0

Factor out the Greatest Common Factor (GCF), 'ln'.
ln(-5 + 2x) = 0
