Solution for ln(x-5)+ln(2x+1)=ln(x^2+12x+11) equation:


Simplifying
ln(x + -5) + ln(2x + 1) = ln(x2 + 12x + 11)

Reorder the terms:
ln(-5 + x) + ln(2x + 1) = ln(x2 + 12x + 11)
(-5 * ln + x * ln) + ln(2x + 1) = ln(x2 + 12x + 11)
(-5ln + lnx) + ln(2x + 1) = ln(x2 + 12x + 11)

Reorder the terms:
-5ln + lnx + ln(1 + 2x) = ln(x2 + 12x + 11)
-5ln + lnx + (1 * ln + 2x * ln) = ln(x2 + 12x + 11)
-5ln + lnx + (1ln + 2lnx) = ln(x2 + 12x + 11)

Reorder the terms:
-5ln + 1ln + lnx + 2lnx = ln(x2 + 12x + 11)

Combine like terms: -5ln + 1ln = -4ln
-4ln + lnx + 2lnx = ln(x2 + 12x + 11)

Combine like terms: lnx + 2lnx = 3lnx
-4ln + 3lnx = ln(x2 + 12x + 11)

Reorder the terms:
-4ln + 3lnx = ln(11 + 12x + x2)
-4ln + 3lnx = (11 * ln + 12x * ln + x2 * ln)
-4ln + 3lnx = (11ln + 12lnx + lnx2)

Solving
-4ln + 3lnx = 11ln + 12lnx + lnx2

Solving for variable 'l'.

Move all terms containing l to the left, all other terms to the right.

Add '-11ln' to each side of the equation.
-4ln + -11ln + 3lnx = 11ln + 12lnx + -11ln + lnx2

Combine like terms: -4ln + -11ln = -15ln
-15ln + 3lnx = 11ln + 12lnx + -11ln + lnx2

Reorder the terms:
-15ln + 3lnx = 11ln + -11ln + 12lnx + lnx2

Combine like terms: 11ln + -11ln = 0
-15ln + 3lnx = 0 + 12lnx + lnx2
-15ln + 3lnx = 12lnx + lnx2

Add '-12lnx' to each side of the equation.
-15ln + 3lnx + -12lnx = 12lnx + -12lnx + lnx2

Combine like terms: 3lnx + -12lnx = -9lnx
-15ln + -9lnx = 12lnx + -12lnx + lnx2

Combine like terms: 12lnx + -12lnx = 0
-15ln + -9lnx = 0 + lnx2
-15ln + -9lnx = lnx2

Add '-1lnx2' to each side of the equation.
-15ln + -9lnx + -1lnx2 = lnx2 + -1lnx2

Combine like terms: lnx2 + -1lnx2 = 0
-15ln + -9lnx + -1lnx2 = 0

Factor out the Greatest Common Factor (GCF), '-1ln'.
-1ln(15 + 9x + x2) = 0

Ignore the factor -1.

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 '(15 + 9x + x2)' equal to zero and attempt to solve: Simplifying 15 + 9x + x2 = 0 Solving 15 + 9x + x2 = 0 Move all terms containing l to the left, all other terms to the right. Add '-15' to each side of the equation. 15 + 9x + -15 + x2 = 0 + -15 Reorder the terms: 15 + -15 + 9x + x2 = 0 + -15 Combine like terms: 15 + -15 = 0 0 + 9x + x2 = 0 + -15 9x + x2 = 0 + -15 Combine like terms: 0 + -15 = -15 9x + x2 = -15 Add '-9x' to each side of the equation. 9x + -9x + x2 = -15 + -9x Combine like terms: 9x + -9x = 0 0 + x2 = -15 + -9x x2 = -15 + -9x Add '-1x2' to each side of the equation. x2 + -1x2 = -15 + -9x + -1x2 Combine like terms: x2 + -1x2 = 0 0 = -15 + -9x + -1x2 Simplifying 0 = -15 + -9x + -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.
