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

Divide each side by '10'.
-9.2 + 0.9x + x2 = 0

Move the constant term to the right:

Add '9.2' to each side of the equation.
-9.2 + 0.9x + 9.2 + x2 = 0 + 9.2

Reorder the terms:
-9.2 + 9.2 + 0.9x + x2 = 0 + 9.2

Combine like terms: -9.2 + 9.2 = 0.0
0.0 + 0.9x + x2 = 0 + 9.2
0.9x + x2 = 0 + 9.2

Combine like terms: 0 + 9.2 = 9.2
0.9x + x2 = 9.2

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 = 9.2 + 0.2025

Reorder the terms:
0.2025 + 0.9x + x2 = 9.2 + 0.2025

Combine like terms: 9.2 + 0.2025 = 9.4025
0.2025 + 0.9x + x2 = 9.4025
