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

Divide each side by '5'.
27.6 + -9.6y + y2 = 0

Move the constant term to the right:

Add '-27.6' to each side of the equation.
27.6 + -9.6y + -27.6 + y2 = 0 + -27.6

Reorder the terms:
27.6 + -27.6 + -9.6y + y2 = 0 + -27.6

Combine like terms: 27.6 + -27.6 = 0.0
0.0 + -9.6y + y2 = 0 + -27.6
-9.6y + y2 = 0 + -27.6

Combine like terms: 0 + -27.6 = -27.6
-9.6y + y2 = -27.6

The y term is -9.6y.  Take half its coefficient (-4.8).
Square it (23.04) and add it to both sides.

Add '23.04' to each side of the equation.
-9.6y + 23.04 + y2 = -27.6 + 23.04
