Solving for variable 'l'.

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

Add '-2lnx' to each side of the equation.
-1ln + lnx + 8lx + -2lnx + lx2 = 2lnx + -2lnx

Reorder the terms:
-1ln + lnx + -2lnx + 8lx + lx2 = 2lnx + -2lnx

Combine like terms: lnx + -2lnx = -1lnx
-1ln + -1lnx + 8lx + lx2 = 2lnx + -2lnx

Combine like terms: 2lnx + -2lnx = 0
-1ln + -1lnx + 8lx + lx2 = 0

Factor out the Greatest Common Factor (GCF), 'l'.
l(-1n + -1nx + 8x + x2) = 0

Subproblem 1

Set the factor 'l' equal to zero and attempt to solve: Simplifying l = 0 Solving l = 0 Move all terms containing l to the left, all other terms to the right. Simplifying l = 0

Subproblem 2

Set the factor '(-1n + -1nx + 8x + x2)' equal to zero and attempt to solve: Simplifying -1n + -1nx + 8x + x2 = 0 Solving -1n + -1nx + 8x + x2 = 0 Move all terms containing l to the left, all other terms to the right. Add 'n' to each side of the equation. -1n + -1nx + 8x + n + x2 = 0 + n Reorder the terms: -1n + n + -1nx + 8x + x2 = 0 + n Combine like terms: -1n + n = 0 0 + -1nx + 8x + x2 = 0 + n -1nx + 8x + x2 = 0 + n Remove the zero: -1nx + 8x + x2 = n Add 'nx' to each side of the equation. -1nx + 8x + nx + x2 = n + nx Reorder the terms: -1nx + nx + 8x + x2 = n + nx Combine like terms: -1nx + nx = 0 0 + 8x + x2 = n + nx 8x + x2 = n + nx Add '-8x' to each side of the equation. 8x + -8x + x2 = n + nx + -8x Combine like terms: 8x + -8x = 0 0 + x2 = n + nx + -8x x2 = n + nx + -8x Add '-1x2' to each side of the equation. x2 + -1x2 = n + nx + -8x + -1x2 Combine like terms: x2 + -1x2 = 0 0 = n + nx + -8x + -1x2 Simplifying 0 = n + nx + -8x + -1x2 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.
