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