Solution for ln(x-1)+ln(x+2)=ln(45) equation:


Simplifying
ln(x + -1) + ln(x + 2) = ln(45)

Reorder the terms:
ln(-1 + x) + ln(x + 2) = ln(45)
(-1 * ln + x * ln) + ln(x + 2) = ln(45)
(-1ln + lnx) + ln(x + 2) = ln(45)

Reorder the terms:
-1ln + lnx + ln(2 + x) = ln(45)
-1ln + lnx + (2 * ln + x * ln) = ln(45)
-1ln + lnx + (2ln + lnx) = ln(45)

Reorder the terms:
-1ln + 2ln + lnx + lnx = ln(45)

Combine like terms: -1ln + 2ln = 1ln
1ln + lnx + lnx = ln(45)

Combine like terms: lnx + lnx = 2lnx
1ln + 2lnx = ln(45)

Reorder the terms for easier multiplication:
1ln + 2lnx = 45ln

Solving
1ln + 2lnx = 45ln

Solving for variable 'l'.

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

Add '-45ln' to each side of the equation.
1ln + -45ln + 2lnx = 45ln + -45ln

Combine like terms: 1ln + -45ln = -44ln
-44ln + 2lnx = 45ln + -45ln

Combine like terms: 45ln + -45ln = 0
-44ln + 2lnx = 0

Factor out the Greatest Common Factor (GCF), '2ln'.
2ln(-22 + x) = 0

Ignore the factor 2.

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 '(-22 + x)' equal to zero and attempt to solve: Simplifying -22 + x = 0 Solving -22 + x = 0 Move all terms containing l to the left, all other terms to the right. Add '22' to each side of the equation. -22 + 22 + x = 0 + 22 Combine like terms: -22 + 22 = 0 0 + x = 0 + 22 x = 0 + 22 Combine like terms: 0 + 22 = 22 x = 22 Add '-1x' to each side of the equation. x + -1x = 22 + -1x Combine like terms: x + -1x = 0 0 = 22 + -1x Simplifying 0 = 22 + -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.
