Solution for ln(4x-1)+ln(x+2)=2ln(x) equation:


Simplifying
ln(4x + -1) + ln(x + 2) = 2ln(x)

Reorder the terms:
ln(-1 + 4x) + ln(x + 2) = 2ln(x)
(-1 * ln + 4x * ln) + ln(x + 2) = 2ln(x)
(-1ln + 4lnx) + ln(x + 2) = 2ln(x)

Reorder the terms:
-1ln + 4lnx + ln(2 + x) = 2ln(x)
-1ln + 4lnx + (2 * ln + x * ln) = 2ln(x)
-1ln + 4lnx + (2ln + lnx) = 2ln(x)

Reorder the terms:
-1ln + 2ln + 4lnx + lnx = 2ln(x)

Combine like terms: -1ln + 2ln = 1ln
1ln + 4lnx + lnx = 2ln(x)

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

Multiply ln * x
1ln + 5lnx = 2lnx

Solving
1ln + 5lnx = 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.
1ln + 5lnx + -2lnx = 2lnx + -2lnx

Combine like terms: 5lnx + -2lnx = 3lnx
1ln + 3lnx = 2lnx + -2lnx

Combine like terms: 2lnx + -2lnx = 0
1ln + 3lnx = 0

Factor out the Greatest Common Factor (GCF), 'ln'.
ln(1 + 3x) = 0

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 '(1 + 3x)' equal to zero and attempt to solve: Simplifying 1 + 3x = 0 Solving 1 + 3x = 0 Move all terms containing l to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + 3x = 0 + -1 Combine like terms: 1 + -1 = 0 0 + 3x = 0 + -1 3x = 0 + -1 Combine like terms: 0 + -1 = -1 3x = -1 Add '-3x' to each side of the equation. 3x + -3x = -1 + -3x Combine like terms: 3x + -3x = 0 0 = -1 + -3x Simplifying 0 = -1 + -3x 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.
