Simplifying ln(x2 + 4) = 2ln(x) + ln(4) Reorder the terms: ln(4 + x2) = 2ln(x) + ln(4) (4 * ln + x2 * ln) = 2ln(x) + ln(4) (4ln + lnx2) = 2ln(x) + ln(4) Multiply ln * x 4ln + lnx2 = 2lnx + ln(4) Reorder the terms for easier multiplication: 4ln + lnx2 = 2lnx + 4ln Reorder the terms: 4ln + lnx2 = 4ln + 2lnx Add '-4ln' to each side of the equation. 4ln + -4ln + lnx2 = 4ln + -4ln + 2lnx Combine like terms: 4ln + -4ln = 0 0 + lnx2 = 4ln + -4ln + 2lnx lnx2 = 4ln + -4ln + 2lnx Combine like terms: 4ln + -4ln = 0 lnx2 = 0 + 2lnx lnx2 = 2lnx Solving lnx2 = 2lnx Solving for variable 'l'. Move all terms containing l to the left, all other terms to the right. Add '-2lnx' to each side of the equation. -2lnx + lnx2 = 2lnx + -2lnx Combine like terms: 2lnx + -2lnx = 0 -2lnx + lnx2 = 0 Factor out the Greatest Common Factor (GCF), 'lnx'. lnx(-2 + x) = 0Subproblem 1
Set the factor 'lnx' equal to zero and attempt to solve: Simplifying lnx = 0 Solving lnx = 0 Move all terms containing l to the left, all other terms to the right. Simplifying lnx = 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.
