Solution for ln(-x)=ln(x^2-6) equation:


Simplifying
ln(-1x) = ln(x2 + -6)

Remove parenthesis around (-1x)
ln * -1x = ln(x2 + -6)

Reorder the terms for easier multiplication:
-1ln * x = ln(x2 + -6)

Multiply ln * x
-1lnx = ln(x2 + -6)

Reorder the terms:
-1lnx = ln(-6 + x2)
-1lnx = (-6 * ln + x2 * ln)
-1lnx = (-6ln + lnx2)

Solving
-1lnx = -6ln + lnx2

Solving for variable 'l'.

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

Add '6ln' to each side of the equation.
6ln + -1lnx = -6ln + 6ln + lnx2

Combine like terms: -6ln + 6ln = 0
6ln + -1lnx = 0 + lnx2
6ln + -1lnx = lnx2

Add '-1lnx2' to each side of the equation.
6ln + -1lnx + -1lnx2 = lnx2 + -1lnx2

Combine like terms: lnx2 + -1lnx2 = 0
6ln + -1lnx + -1lnx2 = 0

Factor out the Greatest Common Factor (GCF), 'ln'.
ln(6 + -1x + -1x2) = 0

Factor a trinomial.
ln((2 + -1x)(3 + x)) = 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 + -1x)' equal to zero and attempt to solve: Simplifying 2 + -1x = 0 Solving 2 + -1x = 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 + -1x = 0 + -2 Combine like terms: 2 + -2 = 0 0 + -1x = 0 + -2 -1x = 0 + -2 Combine like terms: 0 + -2 = -2 -1x = -2 Add 'x' to each side of the equation. -1x + x = -2 + x Combine like terms: -1x + x = 0 0 = -2 + x Simplifying 0 = -2 + x The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.

Subproblem 3

Set the factor '(3 + x)' equal to zero and attempt to solve: Simplifying 3 + x = 0 Solving 3 + x = 0 Move all terms containing l to the left, all other terms to the right. Add '-3' to each side of the equation. 3 + -3 + x = 0 + -3 Combine like terms: 3 + -3 = 0 0 + x = 0 + -3 x = 0 + -3 Combine like terms: 0 + -3 = -3 x = -3 Add '-1x' to each side of the equation. x + -1x = -3 + -1x Combine like terms: x + -1x = 0 0 = -3 + -1x Simplifying 0 = -3 + -1x 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.
