Simplifying ln(4 + x2) = ln (4 * ln + x2 * ln) = ln (4ln + lnx2) = ln Solving 4ln + lnx2 = ln 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. 4ln + -1ln + lnx2 = ln + -1ln Combine like terms: 4ln + -1ln = 3ln 3ln + lnx2 = ln + -1ln Combine like terms: ln + -1ln = 0 3ln + lnx2 = 0 Factor out the Greatest Common Factor (GCF), 'ln'. ln(3 + 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 '(3 + x2)' equal to zero and attempt to solve: Simplifying 3 + x2 = 0 Solving 3 + x2 = 0 Move all terms containing l to the left, all other terms to the right. Add '-3' to each side of the equation. 3 + -3 + x2 = 0 + -3 Combine like terms: 3 + -3 = 0 0 + x2 = 0 + -3 x2 = 0 + -3 Combine like terms: 0 + -3 = -3 x2 = -3 Add '-1x2' to each side of the equation. x2 + -1x2 = -3 + -1x2 Combine like terms: x2 + -1x2 = 0 0 = -3 + -1x2 Simplifying 0 = -3 + -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.
