Solving for variable 'g'.

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

Add '-30glo' to each side of the equation.
-15glox + -30glo + 5glox2 = 30glo + -30glo + 10glox

Reorder the terms:
-30glo + -15glox + 5glox2 = 30glo + -30glo + 10glox

Combine like terms: 30glo + -30glo = 0
-30glo + -15glox + 5glox2 = 0 + 10glox
-30glo + -15glox + 5glox2 = 10glox

Add '-10glox' to each side of the equation.
-30glo + -15glox + -10glox + 5glox2 = 10glox + -10glox

Combine like terms: -15glox + -10glox = -25glox
-30glo + -25glox + 5glox2 = 10glox + -10glox

Combine like terms: 10glox + -10glox = 0
-30glo + -25glox + 5glox2 = 0

Factor out the Greatest Common Factor (GCF), '5glo'.
5glo(-6 + -5x + x2) = 0

Factor a trinomial.
5glo((-1 + -1x)(6 + -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.
