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


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

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

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

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

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

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

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

Solving
4lnx = 2ln + lnx

Solving for variable 'l'.

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

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

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

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

Combine like terms: 4lnx + -1lnx = 3lnx
-2ln + 3lnx = lnx + -1lnx

Combine like terms: lnx + -1lnx = 0
-2ln + 3lnx = 0

Factor out the Greatest Common Factor (GCF), 'ln'.
ln(-2 + 3x) = 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 '(-2 + 3x)' equal to zero and attempt to solve: Simplifying -2 + 3x = 0 Solving -2 + 3x = 0 Move all terms containing l to the left, all other terms to the right. Add '2' to each side of the equation. -2 + 2 + 3x = 0 + 2 Combine like terms: -2 + 2 = 0 0 + 3x = 0 + 2 3x = 0 + 2 Combine like terms: 0 + 2 = 2 3x = 2 Add '-3x' to each side of the equation. 3x + -3x = 2 + -3x Combine like terms: 3x + -3x = 0 0 = 2 + -3x Simplifying 0 = 2 + -3x 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.
