Simplifying ln(x2 + 8) + -1ln(x + 1) = ln(x + 2) Reorder the terms: ln(8 + x2) + -1ln(x + 1) = ln(x + 2) (8 * ln + x2 * ln) + -1ln(x + 1) = ln(x + 2) (8ln + lnx2) + -1ln(x + 1) = ln(x + 2) Reorder the terms: 8ln + lnx2 + -1ln(1 + x) = ln(x + 2) 8ln + lnx2 + (1 * -1ln + x * -1ln) = ln(x + 2) 8ln + lnx2 + (-1ln + -1lnx) = ln(x + 2) Reorder the terms: 8ln + -1ln + -1lnx + lnx2 = ln(x + 2) Combine like terms: 8ln + -1ln = 7ln 7ln + -1lnx + lnx2 = ln(x + 2) Reorder the terms: 7ln + -1lnx + lnx2 = ln(2 + x) 7ln + -1lnx + lnx2 = (2 * ln + x * ln) 7ln + -1lnx + lnx2 = (2ln + lnx) Solving 7ln + -1lnx + lnx2 = 2ln + lnx Solving for variable 'l'. Move all terms containing l to the left, all other terms to the right. Add '-2ln' to each side of the equation. 7ln + -1lnx + -2ln + lnx2 = 2ln + -2ln + lnx Reorder the terms: 7ln + -2ln + -1lnx + lnx2 = 2ln + -2ln + lnx Combine like terms: 7ln + -2ln = 5ln 5ln + -1lnx + lnx2 = 2ln + -2ln + lnx Combine like terms: 2ln + -2ln = 0 5ln + -1lnx + lnx2 = 0 + lnx 5ln + -1lnx + lnx2 = lnx Add '-1lnx' to each side of the equation. 5ln + -1lnx + -1lnx + lnx2 = lnx + -1lnx Combine like terms: -1lnx + -1lnx = -2lnx 5ln + -2lnx + lnx2 = lnx + -1lnx Combine like terms: lnx + -1lnx = 0 5ln + -2lnx + lnx2 = 0 Factor out the Greatest Common Factor (GCF), 'ln'. ln(5 + -2x + x2) = 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 '(5 + -2x + x2)' equal to zero and attempt to solve: Simplifying 5 + -2x + x2 = 0 Solving 5 + -2x + x2 = 0 Move all terms containing l to the left, all other terms to the right. Add '-5' to each side of the equation. 5 + -2x + -5 + x2 = 0 + -5 Reorder the terms: 5 + -5 + -2x + x2 = 0 + -5 Combine like terms: 5 + -5 = 0 0 + -2x + x2 = 0 + -5 -2x + x2 = 0 + -5 Combine like terms: 0 + -5 = -5 -2x + x2 = -5 Add '2x' to each side of the equation. -2x + 2x + x2 = -5 + 2x Combine like terms: -2x + 2x = 0 0 + x2 = -5 + 2x x2 = -5 + 2x Add '-1x2' to each side of the equation. x2 + -1x2 = -5 + 2x + -1x2 Combine like terms: x2 + -1x2 = 0 0 = -5 + 2x + -1x2 Simplifying 0 = -5 + 2x + -1x2 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.
