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

Divide each side by '10'.
0.2 + -1.9x + x2 = 0

Move the constant term to the right:

Add '-0.2' to each side of the equation.
0.2 + -1.9x + -0.2 + x2 = 0 + -0.2

Reorder the terms:
0.2 + -0.2 + -1.9x + x2 = 0 + -0.2

Combine like terms: 0.2 + -0.2 = 0.0
0.0 + -1.9x + x2 = 0 + -0.2
-1.9x + x2 = 0 + -0.2

Combine like terms: 0 + -0.2 = -0.2
-1.9x + x2 = -0.2

The x term is -1.9x.  Take half its coefficient (-0.95).
Square it (0.9025) and add it to both sides.

Add '0.9025' to each side of the equation.
-1.9x + 0.9025 + x2 = -0.2 + 0.9025

Reorder the terms:
0.9025 + -1.9x + x2 = -0.2 + 0.9025

Combine like terms: -0.2 + 0.9025 = 0.7025
0.9025 + -1.9x + x2 = 0.7025

Factor a perfect square on the left side:
(x + -0.95)(x + -0.95) = 0.7025
