10 the coefficient of the squared term: 

Divide each side by '10'.
0.5 + 0.9x + x2 = 0

Move the constant term to the right:

Add '-0.5' to each side of the equation.
0.5 + 0.9x + -0.5 + x2 = 0 + -0.5

Reorder the terms:
0.5 + -0.5 + 0.9x + x2 = 0 + -0.5

Combine like terms: 0.5 + -0.5 = 0.0
0.0 + 0.9x + x2 = 0 + -0.5
0.9x + x2 = 0 + -0.5

Combine like terms: 0 + -0.5 = -0.5
0.9x + x2 = -0.5

The x term is 0.9x.  Take half its coefficient (0.45).
Square it (0.2025) and add it to both sides.

Add '0.2025' to each side of the equation.
0.9x + 0.2025 + x2 = -0.5 + 0.2025

Reorder the terms:
0.2025 + 0.9x + x2 = -0.5 + 0.2025

Combine like terms: -0.5 + 0.2025 = -0.2975
0.2025 + 0.9x + x2 = -0.2975
