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

Divide each side by '0.1'.
-10 + 10x + x2 = 0

Move the constant term to the right:

Add '10' to each side of the equation.
-10 + 10x + 10 + x2 = 0 + 10

Reorder the terms:
-10 + 10 + 10x + x2 = 0 + 10

Combine like terms: -10 + 10 = 0
0 + 10x + x2 = 0 + 10
10x + x2 = 0 + 10

Combine like terms: 0 + 10 = 10
10x + x2 = 10

The x term is x.  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.
10x + 0.25 + x2 = 10 + 0.25

Reorder the terms:
0.25 + 10x + x2 = 10 + 0.25

Combine like terms: 10 + 0.25 = 10.25
0.25 + 10x + x2 = 10.25
