Simplifying ln(x + 1) + ln(x + 3) = 0 Reorder the terms: ln(1 + x) + ln(x + 3) = 0 (1 * ln + x * ln) + ln(x + 3) = 0 (1ln + lnx) + ln(x + 3) = 0 Reorder the terms: 1ln + lnx + ln(3 + x) = 0 1ln + lnx + (3 * ln + x * ln) = 0 1ln + lnx + (3ln + lnx) = 0 Reorder the terms: 1ln + 3ln + lnx + lnx = 0 Combine like terms: 1ln + 3ln = 4ln 4ln + lnx + lnx = 0 Combine like terms: lnx + lnx = 2lnx 4ln + 2lnx = 0 Solving 4ln + 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(2 + 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 '(2 + x)' equal to zero and attempt to solve: Simplifying 2 + x = 0 Solving 2 + x = 0 Move all terms containing l to the left, all other terms to the right. Add '-2' to each side of the equation. 2 + -2 + x = 0 + -2 Combine like terms: 2 + -2 = 0 0 + x = 0 + -2 x = 0 + -2 Combine like terms: 0 + -2 = -2 x = -2 Add '-1x' to each side of the equation. x + -1x = -2 + -1x Combine like terms: x + -1x = 0 0 = -2 + -1x Simplifying 0 = -2 + -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.
