Subproblem 1
Set the factor '(-8 + g + g2)' equal to zero and attempt to solve:

Simplifying
-8 + g + g2 = 0

Solving
-8 + g + g2 = 0

Begin completing the square.

Move the constant term to the right:

Add '8' to each side of the equation.
-8 + g + 8 + g2 = 0 + 8

Reorder the terms:
-8 + 8 + g + g2 = 0 + 8

Combine like terms: -8 + 8 = 0
0 + g + g2 = 0 + 8
g + g2 = 0 + 8

Combine like terms: 0 + 8 = 8
g + g2 = 8

The g term is g.  Take half its coefficient (0.5).
Square it (0.25) and add it to both sides.

Add '0.25' to each side of the equation.
g + 0.25 + g2 = 8 + 0.25

Reorder the terms:
0.25 + g + g2 = 8 + 0.25

Combine like terms: 8 + 0.25 = 8.25
0.25 + g + g2 = 8.25

Factor a perfect square on the left side:
(g + 0.5)(g + 0.5) = 8.25

Calculate the square root of the right side: 2.872281323

g + 0.5 = -2.872281323

Simplifying
g + 0.5 = -2.872281323

Reorder the terms:
0.5 + g = -2.872281323

Solving
0.5 + g = -2.872281323

Solving for variable 'g'.

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

Add '-0.5' to each side of the equation.
0.5 + -0.5 + g = -2.872281323 + -0.5

Combine like terms: 0.5 + -0.5 = 0.0
0.0 + g = -2.872281323 + -0.5
g = -2.872281323 + -0.5

Combine like terms: -2.872281323 + -0.5 = -3.372281323
g = -3.372281323
