Solution for ln(2x+1)(x+2)=2ln(x+2) equation:


Simplifying
ln(2x + 1)(x + 2) = 2ln(x + 2)

Reorder the terms:
ln(1 + 2x)(x + 2) = 2ln(x + 2)

Reorder the terms:
ln(1 + 2x)(2 + x) = 2ln(x + 2)

Multiply (1 + 2x) * (2 + x)
ln(1(2 + x) + 2x * (2 + x)) = 2ln(x + 2)
ln((2 * 1 + x * 1) + 2x * (2 + x)) = 2ln(x + 2)
ln((2 + 1x) + 2x * (2 + x)) = 2ln(x + 2)
ln(2 + 1x + (2 * 2x + x * 2x)) = 2ln(x + 2)
ln(2 + 1x + (4x + 2x2)) = 2ln(x + 2)

Combine like terms: 1x + 4x = 5x
ln(2 + 5x + 2x2) = 2ln(x + 2)
(2 * ln + 5x * ln + 2x2 * ln) = 2ln(x + 2)
(2ln + 5lnx + 2lnx2) = 2ln(x + 2)

Reorder the terms:
2ln + 5lnx + 2lnx2 = 2ln(2 + x)
2ln + 5lnx + 2lnx2 = (2 * 2ln + x * 2ln)
2ln + 5lnx + 2lnx2 = (4ln + 2lnx)

Solving
2ln + 5lnx + 2lnx2 = 4ln + 2lnx

Solving for variable 'l'.

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

Add '-4ln' to each side of the equation.
2ln + 5lnx + -4ln + 2lnx2 = 4ln + -4ln + 2lnx

Combine like terms: 2ln + -4ln = -2ln
-2ln + 5lnx + 2lnx2 = 4ln + -4ln + 2lnx

Combine like terms: 4ln + -4ln = 0
-2ln + 5lnx + 2lnx2 = 0 + 2lnx
-2ln + 5lnx + 2lnx2 = 2lnx

Add '-2lnx' to each side of the equation.
-2ln + 5lnx + -2lnx + 2lnx2 = 2lnx + -2lnx

Combine like terms: 5lnx + -2lnx = 3lnx
-2ln + 3lnx + 2lnx2 = 2lnx + -2lnx

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

Factor out the Greatest Common Factor (GCF), 'ln'.
ln(-2 + 3x + 2x2) = 0
