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


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

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

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

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

Multiply ln * x
2ln + -1lnx + 2nL + nxL = lnx

Solving
2ln + -1lnx + 2nL + nxL = lnx

Solving for variable 'l'.

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

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

Reorder the terms:
2ln + -1lnx + -1lnx + 2nL + nxL = lnx + -1lnx

Combine like terms: -1lnx + -1lnx = -2lnx
2ln + -2lnx + 2nL + nxL = lnx + -1lnx

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

Add '-2nL' to each side of the equation.
2ln + -2lnx + 2nL + -2nL + nxL = 0 + -2nL

Combine like terms: 2nL + -2nL = 0
2ln + -2lnx + 0 + nxL = 0 + -2nL
2ln + -2lnx + nxL = 0 + -2nL
Remove the zero:
2ln + -2lnx + nxL = -2nL

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

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

Reorder the terms:
2ln + -2lnx + 2nL + nxL = -2nL + 2nL + -1nxL + nxL

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

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

Factor out the Greatest Common Factor (GCF), 'n'.
n(2l + -2lx + 2L + xL) = 0

Subproblem 1

Set the factor 'n' equal to zero and attempt to solve: Simplifying n = 0 Solving n = 0 Move all terms containing l to the left, all other terms to the right. Add '-1n' to each side of the equation. n + -1n = 0 + -1n Remove the zero: 0 = -1n Simplifying 0 = -1n 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 '(2l + -2lx + 2L + xL)' equal to zero and attempt to solve: Simplifying 2l + -2lx + 2L + xL = 0 Reorder the terms: 2L + 2l + -2lx + xL = 0 Solving 2L + 2l + -2lx + xL = 0 Move all terms containing l to the left, all other terms to the right. Add '-2L' to each side of the equation. 2L + 2l + -2lx + -2L + xL = 0 + -2L Reorder the terms: 2L + -2L + 2l + -2lx + xL = 0 + -2L Combine like terms: 2L + -2L = 0 0 + 2l + -2lx + xL = 0 + -2L 2l + -2lx + xL = 0 + -2L Remove the zero: 2l + -2lx + xL = -2L Add '-1xL' to each side of the equation. 2l + -2lx + xL + -1xL = -2L + -1xL Combine like terms: xL + -1xL = 0 2l + -2lx + 0 = -2L + -1xL 2l + -2lx = -2L + -1xL 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.
