Solution for log(x+1)+log(x-1)=log(8) equation:


Simplifying
log(x + 1) + log(x + -1) = log(8)

Reorder the terms:
glo(1 + x) + log(x + -1) = log(8)
(1 * glo + x * glo) + log(x + -1) = log(8)
(1glo + glox) + log(x + -1) = log(8)

Reorder the terms:
1glo + glox + glo(-1 + x) = log(8)
1glo + glox + (-1 * glo + x * glo) = log(8)
1glo + glox + (-1glo + glox) = log(8)

Reorder the terms:
1glo + -1glo + glox + glox = log(8)

Combine like terms: 1glo + -1glo = 0
0 + glox + glox = log(8)
glox + glox = log(8)

Combine like terms: glox + glox = 2glox
2glox = log(8)

Reorder the terms for easier multiplication:
2glox = 8glo

Solving
2glox = 8glo

Solving for variable 'g'.

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

Add '-8glo' to each side of the equation.
-8glo + 2glox = 8glo + -8glo

Combine like terms: 8glo + -8glo = 0
-8glo + 2glox = 0

Factor out the Greatest Common Factor (GCF), '2glo'.
2glo(-4 + x) = 0

Ignore the factor 2.

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 '(-4 + x)' equal to zero and attempt to solve: Simplifying -4 + x = 0 Solving -4 + x = 0 Move all terms containing g to the left, all other terms to the right. Add '4' to each side of the equation. -4 + 4 + x = 0 + 4 Combine like terms: -4 + 4 = 0 0 + x = 0 + 4 x = 0 + 4 Combine like terms: 0 + 4 = 4 x = 4 Add '-1x' to each side of the equation. x + -1x = 4 + -1x Combine like terms: x + -1x = 0 0 = 4 + -1x Simplifying 0 = 4 + -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.
