Add '3' to each side of the equation.
-3 + g + 3 + g2 = 0 + 3

Reorder the terms:
-3 + 3 + g + g2 = 0 + 3

Combine like terms: -3 + 3 = 0
0 + g + g2 = 0 + 3
g + g2 = 0 + 3

Combine like terms: 0 + 3 = 3
g + g2 = 3

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 = 3 + 0.25

Reorder the terms:
0.25 + g + g2 = 3 + 0.25

Combine like terms: 3 + 0.25 = 3.25
0.25 + g + g2 = 3.25

Factor a perfect square on the left side:
(g + 0.5)(g + 0.5) = 3.25
