-144glo + 12glox2 = 0 + 12glox
-144glo + 12glox2 = 12glox

Add '-12glox' to each side of the equation.
-144glo + -12glox + 12glox2 = 12glox + -12glox

Combine like terms: 12glox + -12glox = 0
-144glo + -12glox + 12glox2 = 0

Factor out the Greatest Common Factor (GCF), '12glo'.
12glo(-12 + -1x + x2) = 0

Factor a trinomial.
12glo((-3 + -1x)(4 + -1x)) = 0

Ignore the factor 12.

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.
