Solution for ln((3x+2)(x+2))=2ln(x+2) equation:


Simplifying
ln((3x + 2)(x + 2)) = 2ln(x + 2)

Reorder the terms:
ln((2 + 3x)(x + 2)) = 2ln(x + 2)

Reorder the terms:
ln((2 + 3x)(2 + x)) = 2ln(x + 2)

Multiply (2 + 3x) * (2 + x)
ln((2(2 + x) + 3x * (2 + x))) = 2ln(x + 2)
ln(((2 * 2 + x * 2) + 3x * (2 + x))) = 2ln(x + 2)
ln(((4 + 2x) + 3x * (2 + x))) = 2ln(x + 2)
ln((4 + 2x + (2 * 3x + x * 3x))) = 2ln(x + 2)
ln((4 + 2x + (6x + 3x2))) = 2ln(x + 2)

Combine like terms: 2x + 6x = 8x
ln((4 + 8x + 3x2)) = 2ln(x + 2)
(4 * ln + 8x * ln + 3x2 * ln) = 2ln(x + 2)
(4ln + 8lnx + 3lnx2) = 2ln(x + 2)

Reorder the terms:
4ln + 8lnx + 3lnx2 = 2ln(2 + x)
4ln + 8lnx + 3lnx2 = (2 * 2ln + x * 2ln)
4ln + 8lnx + 3lnx2 = (4ln + 2lnx)

Add '-4ln' to each side of the equation.
4ln + 8lnx + -4ln + 3lnx2 = 4ln + -4ln + 2lnx

Reorder the terms:
4ln + -4ln + 8lnx + 3lnx2 = 4ln + -4ln + 2lnx

Combine like terms: 4ln + -4ln = 0
0 + 8lnx + 3lnx2 = 4ln + -4ln + 2lnx
8lnx + 3lnx2 = 4ln + -4ln + 2lnx

Combine like terms: 4ln + -4ln = 0
8lnx + 3lnx2 = 0 + 2lnx
8lnx + 3lnx2 = 2lnx

Solving
8lnx + 3lnx2 = 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.
8lnx + -2lnx + 3lnx2 = 2lnx + -2lnx

Combine like terms: 8lnx + -2lnx = 6lnx
6lnx + 3lnx2 = 2lnx + -2lnx

Combine like terms: 2lnx + -2lnx = 0
6lnx + 3lnx2 = 0

Factor out the Greatest Common Factor (GCF), '3lnx'.
3lnx(2 + x) = 0

Ignore the factor 3.

Subproblem 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.
