-0.8888888889 + 0.8888888889 + h + h2 = 0 + 0.8888888889

Combine like terms: -0.8888888889 + 0.8888888889 = 0.0000000000
0.0000000000 + h + h2 = 0 + 0.8888888889
h + h2 = 0 + 0.8888888889

Combine like terms: 0 + 0.8888888889 = 0.8888888889
h + h2 = 0.8888888889

The h term is h.  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.
 + 0.25 + h2 = 0.8888888889 + 0.25

Combine like terms:  + 0.25 = 1.25
1.25 + h2 = 0.8888888889 + 0.25
