Solution for ln(x-3)+ln(x-2)=ln(x+1) equation:


Simplifying
ln(x + -3) + ln(x + -2) = ln(x + 1)

Reorder the terms:
ln(-3 + x) + ln(x + -2) = ln(x + 1)
(-3 * ln + x * ln) + ln(x + -2) = ln(x + 1)
(-3ln + lnx) + ln(x + -2) = ln(x + 1)

Reorder the terms:
-3ln + lnx + ln(-2 + x) = ln(x + 1)
-3ln + lnx + (-2 * ln + x * ln) = ln(x + 1)
-3ln + lnx + (-2ln + lnx) = ln(x + 1)

Reorder the terms:
-3ln + -2ln + lnx + lnx = ln(x + 1)

Combine like terms: -3ln + -2ln = -5ln
-5ln + lnx + lnx = ln(x + 1)

Combine like terms: lnx + lnx = 2lnx
-5ln + 2lnx = ln(x + 1)

Reorder the terms:
-5ln + 2lnx = ln(1 + x)
-5ln + 2lnx = (1 * ln + x * ln)
-5ln + 2lnx = (1ln + lnx)

Solving
-5ln + 2lnx = 1ln + lnx

Solving for variable 'l'.

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

Add '-1ln' to each side of the equation.
-5ln + -1ln + 2lnx = 1ln + -1ln + lnx

Combine like terms: -5ln + -1ln = -6ln
-6ln + 2lnx = 1ln + -1ln + lnx

Combine like terms: 1ln + -1ln = 0
-6ln + 2lnx = 0 + lnx
-6ln + 2lnx = lnx

Add '-1lnx' to each side of the equation.
-6ln + 2lnx + -1lnx = lnx + -1lnx

Combine like terms: 2lnx + -1lnx = 1lnx
-6ln + 1lnx = lnx + -1lnx

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

Factor out the Greatest Common Factor (GCF), 'ln'.
ln(-6 + 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 '(-6 + x)' equal to zero and attempt to solve: Simplifying -6 + x = 0 Solving -6 + x = 0 Move all terms containing l to the left, all other terms to the right. Add '6' to each side of the equation. -6 + 6 + x = 0 + 6 Combine like terms: -6 + 6 = 0 0 + x = 0 + 6 x = 0 + 6 Combine like terms: 0 + 6 = 6 x = 6 Add '-1x' to each side of the equation. x + -1x = 6 + -1x Combine like terms: x + -1x = 0 0 = 6 + -1x Simplifying 0 = 6 + -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.
