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


Simplifying
log(x) + log(x + -2) = log(x + 4)

Multiply glo * x
glox + log(x + -2) = log(x + 4)

Reorder the terms:
glox + glo(-2 + x) = log(x + 4)
glox + (-2 * glo + x * glo) = log(x + 4)
glox + (-2glo + glox) = log(x + 4)

Reorder the terms:
-2glo + glox + glox = log(x + 4)

Combine like terms: glox + glox = 2glox
-2glo + 2glox = log(x + 4)

Reorder the terms:
-2glo + 2glox = glo(4 + x)
-2glo + 2glox = (4 * glo + x * glo)
-2glo + 2glox = (4glo + glox)

Solving
-2glo + 2glox = 4glo + glox

Solving for variable 'g'.

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

Add '-4glo' to each side of the equation.
-2glo + -4glo + 2glox = 4glo + -4glo + glox

Combine like terms: -2glo + -4glo = -6glo
-6glo + 2glox = 4glo + -4glo + glox

Combine like terms: 4glo + -4glo = 0
-6glo + 2glox = 0 + glox
-6glo + 2glox = glox

Add '-1glox' to each side of the equation.
-6glo + 2glox + -1glox = glox + -1glox

Combine like terms: 2glox + -1glox = 1glox
-6glo + 1glox = glox + -1glox

Combine like terms: glox + -1glox = 0
-6glo + 1glox = 0

Factor out the Greatest Common Factor (GCF), 'glo'.
glo(-6 + x) = 0

Subproblem 1

Set the factor 'glo' equal to zero and attempt to solve: Simplifying glo = 0 Solving glo = 0 Move all terms containing g to the left, all other terms to the right. Simplifying glo = 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 '(-6 + x)' equal to zero and attempt to solve: Simplifying -6 + x = 0 Solving -6 + x = 0 Move all terms containing g to the left, all other terms to the right. Add '6' to each side of the equation. -6 + 6 + x = 0 + 6 Combine like terms: -6 + 6 = 0 0 + x = 0 + 6 x = 0 + 6 Combine like terms: 0 + 6 = 6 x = 6 Add '-1x' to each side of the equation. x + -1x = 6 + -1x Combine like terms: x + -1x = 0 0 = 6 + -1x Simplifying 0 = 6 + -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.
