Simplifying ln(x) + ln(x + -2) = ln(4x) Multiply ln * x lnx + ln(x + -2) = ln(4x) Reorder the terms: lnx + ln(-2 + x) = ln(4x) lnx + (-2 * ln + x * ln) = ln(4x) lnx + (-2ln + lnx) = ln(4x) Reorder the terms: -2ln + lnx + lnx = ln(4x) Combine like terms: lnx + lnx = 2lnx -2ln + 2lnx = ln(4x) Remove parenthesis around (4x) -2ln + 2lnx = ln * 4x Reorder the terms for easier multiplication: -2ln + 2lnx = 4ln * x Multiply ln * x -2ln + 2lnx = 4lnx Solving -2ln + 2lnx = 4lnx Solving for variable 'l'. Move all terms containing l to the left, all other terms to the right. Add '-4lnx' to each side of the equation. -2ln + 2lnx + -4lnx = 4lnx + -4lnx Combine like terms: 2lnx + -4lnx = -2lnx -2ln + -2lnx = 4lnx + -4lnx Combine like terms: 4lnx + -4lnx = 0 -2ln + -2lnx = 0 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.
