5 the coefficient of the squared term: 

Divide each side by '5'.
0.4 + 0.4y + y2 = 0

Move the constant term to the right:

Add '-0.4' to each side of the equation.
0.4 + 0.4y + -0.4 + y2 = 0 + -0.4

Reorder the terms:
0.4 + -0.4 + 0.4y + y2 = 0 + -0.4

Combine like terms: 0.4 + -0.4 = 0.0
0.0 + 0.4y + y2 = 0 + -0.4
0.4y + y2 = 0 + -0.4

Combine like terms: 0 + -0.4 = -0.4
0.4y + y2 = -0.4

The y term is 0.4y.  Take half its coefficient (0.2).
