Solving for variable 'x'.

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

Divide each side by '5'.
0.4 + -4.6x + x2 = 0

Move the constant term to the right:

Add '-0.4' to each side of the equation.
0.4 + -4.6x + -0.4 + x2 = 0 + -0.4

Reorder the terms:
0.4 + -0.4 + -4.6x + x2 = 0 + -0.4

Combine like terms: 0.4 + -0.4 = 0.0
0.0 + -4.6x + x2 = 0 + -0.4
-4.6x + x2 = 0 + -0.4

Combine like terms: 0 + -0.4 = -0.4
-4.6x + x2 = -0.4

The x term is -4.6x.  Take half its coefficient (-2.3).
Square it (5.29) and add it to both sides.

Add '5.29' to each side of the equation.
-4.6x + 5.29 + x2 = -0.4 + 5.29

Reorder the terms:
5.29 + -4.6x + x2 = -0.4 + 5.29

Combine like terms: -0.4 + 5.29 = 4.89
5.29 + -4.6x + x2 = 4.89
