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.
