Simplifying ln(x + -1) + ln(x + 2) = ln(4) Reorder the terms: ln(-1 + x) + ln(x + 2) = ln(4) (-1 * ln + x * ln) + ln(x + 2) = ln(4) (-1ln + lnx) + ln(x + 2) = ln(4) Reorder the terms: -1ln + lnx + ln(2 + x) = ln(4) -1ln + lnx + (2 * ln + x * ln) = ln(4) -1ln + lnx + (2ln + lnx) = ln(4) Reorder the terms: -1ln + 2ln + lnx + lnx = ln(4) Combine like terms: -1ln + 2ln = 1ln 1ln + lnx + lnx = ln(4) Combine like terms: lnx + lnx = 2lnx 1ln + 2lnx = ln(4) Reorder the terms for easier multiplication: 1ln + 2lnx = 4ln Solving 1ln + 2lnx = 4ln 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. 1ln + -4ln + 2lnx = 4ln + -4ln Combine like terms: 1ln + -4ln = -3ln -3ln + 2lnx = 4ln + -4ln Combine like terms: 4ln + -4ln = 0 -3ln + 2lnx = 0 Factor out the Greatest Common Factor (GCF), 'ln'. ln(-3 + 2x) = 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 + 2x)' equal to zero and attempt to solve: Simplifying -3 + 2x = 0 Solving -3 + 2x = 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 + 2x = 0 + 3 Combine like terms: -3 + 3 = 0 0 + 2x = 0 + 3 2x = 0 + 3 Combine like terms: 0 + 3 = 3 2x = 3 Add '-2x' to each side of the equation. 2x + -2x = 3 + -2x Combine like terms: 2x + -2x = 0 0 = 3 + -2x Simplifying 0 = 3 + -2x 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.
