5 the coefficient of the squared term: 

Divide each side by '5'.
-2.8 + 0.8y + y2 = 0

Move the constant term to the right:

Add '2.8' to each side of the equation.
-2.8 + 0.8y + 2.8 + y2 = 0 + 2.8

Reorder the terms:
-2.8 + 2.8 + 0.8y + y2 = 0 + 2.8

Combine like terms: -2.8 + 2.8 = 0.0
0.0 + 0.8y + y2 = 0 + 2.8
0.8y + y2 = 0 + 2.8

Combine like terms: 0 + 2.8 = 2.8
0.8y + y2 = 2.8

The y term is 0.8y.  Take half its coefficient (0.4).
Square it (0.16) and add it to both sides.

Add '0.16' to each side of the equation.
0.8y + 0.16 + y2 = 2.8 + 0.16

Reorder the terms:
0.16 + 0.8y + y2 = 2.8 + 0.16

Combine like terms: 2.8 + 0.16 = 2.96
0.16 + 0.8y + y2 = 2.96
