Simplifying ln(x + 4) + ln(x + -2) = 0 Reorder the terms: ln(4 + x) + ln(x + -2) = 0 (4 * ln + x * ln) + ln(x + -2) = 0 (4ln + lnx) + ln(x + -2) = 0 Reorder the terms: 4ln + lnx + ln(-2 + x) = 0 4ln + lnx + (-2 * ln + x * ln) = 0 4ln + lnx + (-2ln + lnx) = 0 Reorder the terms: 4ln + -2ln + lnx + lnx = 0 Combine like terms: 4ln + -2ln = 2ln 2ln + lnx + lnx = 0 Combine like terms: lnx + lnx = 2lnx 2ln + 2lnx = 0 Solving 2ln + 2lnx = 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), '2ln'. 2ln(1 + x) = 0 Ignore the factor 2.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 + x)' equal to zero and attempt to solve: Simplifying 1 + x = 0 Solving 1 + x = 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 + x = 0 + -1 Combine like terms: 1 + -1 = 0 0 + x = 0 + -1 x = 0 + -1 Combine like terms: 0 + -1 = -1 x = -1 Add '-1x' to each side of the equation. x + -1x = -1 + -1x Combine like terms: x + -1x = 0 0 = -1 + -1x Simplifying 0 = -1 + -1x 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.
