3ln + 2lnx = -5ln + 5ln + lnx2

Combine like terms: -5ln + 5ln = 0
3ln + 2lnx = 0 + lnx2
3ln + 2lnx = lnx2

Add '-1lnx2' to each side of the equation.
3ln + 2lnx + -1lnx2 = lnx2 + -1lnx2

Combine like terms: lnx2 + -1lnx2 = 0
3ln + 2lnx + -1lnx2 = 0

Factor out the Greatest Common Factor (GCF), 'ln'.
ln(3 + 2x + -1x2) = 0

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