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

Divide each side by '25'.
-0.4 + -0.92x + x2 = 0

Move the constant term to the right:

Add '0.4' to each side of the equation.
-0.4 + -0.92x + 0.4 + x2 = 0 + 0.4

Reorder the terms:
-0.4 + 0.4 + -0.92x + x2 = 0 + 0.4

Combine like terms: -0.4 + 0.4 = 0.0
0.0 + -0.92x + x2 = 0 + 0.4
-0.92x + x2 = 0 + 0.4

Combine like terms: 0 + 0.4 = 0.4
-0.92x + x2 = 0.4

The x term is -0.92x.  Take half its coefficient (-0.46).
Square it (0.2116) and add it to both sides.

Add '0.2116' to each side of the equation.
-0.92x + 0.2116 + x2 = 0.4 + 0.2116

Reorder the terms:
0.2116 + -0.92x + x2 = 0.4 + 0.2116

Combine like terms: 0.4 + 0.2116 = 0.6116
0.2116 + -0.92x + x2 = 0.6116
