9ln + 8lnx = -9ln + 9ln + lnx2

Combine like terms: -9ln + 9ln = 0
9ln + 8lnx = 0 + lnx2
9ln + 8lnx = lnx2

Add '-1lnx2' to each side of the equation.
9ln + 8lnx + -1lnx2 = lnx2 + -1lnx2

Combine like terms: lnx2 + -1lnx2 = 0
9ln + 8lnx + -1lnx2 = 0

Factor out the Greatest Common Factor (GCF), 'ln'.
ln(9 + 8x + -1x2) = 0

Factor a trinomial.
ln((9 + -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 '(9 + -1x)' equal to zero and attempt to solve: Simplifying 9 + -1x = 0 Solving 9 + -1x = 0 Move all terms containing l to the left, all other terms to the right. Add '-9' to each side of the equation. 9 + -9 + -1x = 0 + -9 Combine like terms: 9 + -9 = 0 0 + -1x = 0 + -9 -1x = 0 + -9 Combine like terms: 0 + -9 = -9 -1x = -9 Add 'x' to each side of the equation. -1x + x = -9 + x Combine like terms: -1x + x = 0 0 = -9 + x Simplifying 0 = -9 + x The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.

Subproblem 3
