Combine like terms: 15glo + -15glo = 0
-100glo + 5glox2 = 0 + 5glox
-100glo + 5glox2 = 5glox

Add '-5glox' to each side of the equation.
-100glo + -5glox + 5glox2 = 5glox + -5glox

Combine like terms: 5glox + -5glox = 0
-100glo + -5glox + 5glox2 = 0

Factor out the Greatest Common Factor (GCF), '5glo'.
5glo(-20 + -1x + x2) = 0

Factor a trinomial.
5glo((-4 + -1x)(5 + -1x)) = 0

Ignore the factor 5.

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
