Solution for 0=ln(x)+ln(2x+6) equation:


Simplifying
0 = ln(x) + ln(2x + 6)

Multiply ln * x
0 = lnx + ln(2x + 6)

Reorder the terms:
0 = lnx + ln(6 + 2x)
0 = lnx + (6 * ln + 2x * ln)
0 = lnx + (6ln + 2lnx)

Reorder the terms:
0 = 6ln + lnx + 2lnx

Combine like terms: lnx + 2lnx = 3lnx
0 = 6ln + 3lnx

Solving
0 = 6ln + 3lnx

Solving for variable 'l'.

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

Add '-6ln' to each side of the equation.
0 + -6ln = 6ln + -6ln + 3lnx
Remove the zero:
-6ln = 6ln + -6ln + 3lnx

Combine like terms: 6ln + -6ln = 0
-6ln = 0 + 3lnx
-6ln = 3lnx

Add '-3lnx' to each side of the equation.
-6ln + -3lnx = 3lnx + -3lnx

Combine like terms: 3lnx + -3lnx = 0
-6ln + -3lnx = 0

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

Ignore the factor -3.

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 '(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.
