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


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

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

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

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

Combine like terms: 2ln + -2ln = 0
0 + lnx + lnx = ln(-2x + -1)
lnx + lnx = ln(-2x + -1)

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

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

Solving
2lnx = -1ln + -2lnx

Solving for variable 'l'.

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

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

Combine like terms: -1ln + ln = 0
ln + 2lnx = 0 + -2lnx
ln + 2lnx = -2lnx

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

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

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

Factor out the Greatest Common Factor (GCF), 'ln'.
ln(1 + 4x) = 0

Subproblem 1

Set the factor 'ln' equal to zero and attempt to solve: Simplifying ln = 0 Solving ln = 0 Move all terms containing l to the left, all other terms to the right. Simplifying ln = 0 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.

Subproblem 2

Set the factor '(1 + 4x)' equal to zero and attempt to solve: Simplifying 1 + 4x = 0 Solving 1 + 4x = 0 Move all terms containing l to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + 4x = 0 + -1 Combine like terms: 1 + -1 = 0 0 + 4x = 0 + -1 4x = 0 + -1 Combine like terms: 0 + -1 = -1 4x = -1 Add '-4x' to each side of the equation. 4x + -4x = -1 + -4x Combine like terms: 4x + -4x = 0 0 = -1 + -4x Simplifying 0 = -1 + -4x The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined. The solution to this equation could not be determined.
