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

Divide each side by '5'.
0.4 + -1.2x + x2 = 0

Move the constant term to the right:

Add '-0.4' to each side of the equation.
0.4 + -1.2x + -0.4 + x2 = 0 + -0.4

Reorder the terms:
0.4 + -0.4 + -1.2x + x2 = 0 + -0.4

Combine like terms: 0.4 + -0.4 = 0.0
0.0 + -1.2x + x2 = 0 + -0.4
-1.2x + x2 = 0 + -0.4

Combine like terms: 0 + -0.4 = -0.4
-1.2x + x2 = -0.4

The x term is -1.2x.  Take half its coefficient (-0.6).
Square it (0.36) and add it to both sides.

Add '0.36' to each side of the equation.
-1.2x + 0.36 + x2 = -0.4 + 0.36

Reorder the terms:
0.36 + -1.2x + x2 = -0.4 + 0.36

Combine like terms: -0.4 + 0.36 = -0.04
0.36 + -1.2x + x2 = -0.04

Factor a perfect square on the left side:
(x + -0.6)(x + -0.6) = -0.04

Can't calculate square root of the right side.
