3lnx + -3lnx2 = -1 * 81lnx

Multiply -1 * 81
3lnx + -3lnx2 = -81lnx

Solving
3lnx + -3lnx2 = -81lnx

Solving for variable 'l'.

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

Add '81lnx' to each side of the equation.
3lnx + 81lnx + -3lnx2 = -81lnx + 81lnx

Combine like terms: 3lnx + 81lnx = 84lnx
84lnx + -3lnx2 = -81lnx + 81lnx

Combine like terms: -81lnx + 81lnx = 0
84lnx + -3lnx2 = 0

Factor out the Greatest Common Factor (GCF), '3lnx'.
3lnx(28 + -1x) = 0

Ignore the factor 3.

Subproblem 1

Set the factor 'lnx' equal to zero and attempt to solve: Simplifying lnx = 0 Solving lnx = 0 Move all terms containing l to the left, all other terms to the right. Simplifying lnx = 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 '(28 + -1x)' equal to zero and attempt to solve: Simplifying 28 + -1x = 0 Solving 28 + -1x = 0 Move all terms containing l to the left, all other terms to the right. Add '-28' to each side of the equation. 28 + -28 + -1x = 0 + -28 Combine like terms: 28 + -28 = 0 0 + -1x = 0 + -28 -1x = 0 + -28 Combine like terms: 0 + -28 = -28 -1x = -28 Add 'x' to each side of the equation. -1x + x = -28 + x Combine like terms: -1x + x = 0 0 = -28 + x Simplifying 0 = -28 + x 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.
