Begin completing the square.  Divide all terms by
100 the coefficient of the squared term: 

Divide each side by '100'.
1.44 + 2.49g + g2 = 0

Move the constant term to the right:

Add '-1.44' to each side of the equation.
1.44 + 2.49g + -1.44 + g2 = 0 + -1.44

Reorder the terms:
1.44 + -1.44 + 2.49g + g2 = 0 + -1.44

Combine like terms: 1.44 + -1.44 = 0.00
0.00 + 2.49g + g2 = 0 + -1.44
2.49g + g2 = 0 + -1.44

Combine like terms: 0 + -1.44 = -1.44
2.49g + g2 = -1.44

The g term is 2.49g.  Take half its coefficient (1.245).
Square it (1.550025) and add it to both sides.

Add '1.550025' to each side of the equation.
2.49g + 1.550025 + g2 = -1.44 + 1.550025

Reorder the terms:
1.550025 + 2.49g + g2 = -1.44 + 1.550025

Combine like terms: -1.44 + 1.550025 = 0.110025
1.550025 + 2.49g + g2 = 0.110025
