Simplifying 0 = ln[x2 + 1] Reorder the terms: 0 = ln[1 + x2] 0 = [1 * ln + x2 * ln] 0 = [1ln + lnx2] Solving 0 = 1ln + lnx2 Solving for variable 'l'. Move all terms containing l to the left, all other terms to the right. Add '-1ln' to each side of the equation. 0 + -1ln = 1ln + -1ln + lnx2 Remove the zero: -1ln = 1ln + -1ln + lnx2 Combine like terms: 1ln + -1ln = 0 -1ln = 0 + lnx2 -1ln = lnx2 Add '-1lnx2' to each side of the equation. -1ln + -1lnx2 = lnx2 + -1lnx2 Combine like terms: lnx2 + -1lnx2 = 0 -1ln + -1lnx2 = 0 Factor out the Greatest Common Factor (GCF), '-1ln'. -1ln(1 + x2) = 0 Ignore the factor -1.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 '(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.
