-1glo + glox2 = glo(5 + x)
-1glo + glox2 = (5 * glo + x * glo)
-1glo + glox2 = (5glo + glox)

Solving
-1glo + glox2 = 5glo + glox

Solving for variable 'g'.

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

Add '-5glo' to each side of the equation.
-1glo + -5glo + glox2 = 5glo + -5glo + glox

Combine like terms: -1glo + -5glo = -6glo
-6glo + glox2 = 5glo + -5glo + glox

Combine like terms: 5glo + -5glo = 0
-6glo + glox2 = 0 + glox
-6glo + glox2 = glox

Add '-1glox' to each side of the equation.
-6glo + -1glox + glox2 = glox + -1glox

Combine like terms: glox + -1glox = 0
-6glo + -1glox + glox2 = 0

Factor out the Greatest Common Factor (GCF), 'glo'.
glo(-6 + -1x + x2) = 0

Factor a trinomial.
glo((-2 + -1x)(3 + -1x)) = 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.
