Simplifying ln(x2 + -1) + -1ln(x + -1) + ln(x + 1) = 0 Reorder the terms: ln(-1 + x2) + -1ln(x + -1) + ln(x + 1) = 0 (-1 * ln + x2 * ln) + -1ln(x + -1) + ln(x + 1) = 0 (-1ln + lnx2) + -1ln(x + -1) + ln(x + 1) = 0 Reorder the terms: -1ln + lnx2 + -1ln(-1 + x) + ln(x + 1) = 0 -1ln + lnx2 + (-1 * -1ln + x * -1ln) + ln(x + 1) = 0 -1ln + lnx2 + (1ln + -1lnx) + ln(x + 1) = 0 Reorder the terms: -1ln + lnx2 + 1ln + -1lnx + ln(1 + x) = 0 -1ln + lnx2 + 1ln + -1lnx + (1 * ln + x * ln) = 0 -1ln + lnx2 + 1ln + -1lnx + (1ln + lnx) = 0 Reorder the terms: -1ln + 1ln + 1ln + -1lnx + lnx + lnx2 = 0 Combine like terms: -1ln + 1ln = 0 0 + 1ln + -1lnx + lnx + lnx2 = 0 1ln + -1lnx + lnx + lnx2 = 0 Combine like terms: -1lnx + lnx = 0 1ln + 0 + lnx2 = 0 1ln + lnx2 = 0 Solving 1ln + lnx2 = 0 Solving for variable 'l'. Move all terms containing l to the left, all other terms to the right. Factor out the Greatest Common Factor (GCF), 'ln'. ln(1 + x2) = 0Subproblem 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 '(1 + x2)' equal to zero and attempt to solve: Simplifying 1 + x2 = 0 Solving 1 + x2 = 0 Move all terms containing l to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + x2 = 0 + -1 Combine like terms: 1 + -1 = 0 0 + x2 = 0 + -1 x2 = 0 + -1 Combine like terms: 0 + -1 = -1 x2 = -1 Add '-1x2' to each side of the equation. x2 + -1x2 = -1 + -1x2 Combine like terms: x2 + -1x2 = 0 0 = -1 + -1x2 Simplifying 0 = -1 + -1x2 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.
