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

Divide each side by '25'.
-0.56 + -1.32y + y2 = 0

Move the constant term to the right:

Add '0.56' to each side of the equation.
-0.56 + -1.32y + 0.56 + y2 = 0 + 0.56

Reorder the terms:
-0.56 + 0.56 + -1.32y + y2 = 0 + 0.56

Combine like terms: -0.56 + 0.56 = 0.00
0.00 + -1.32y + y2 = 0 + 0.56
-1.32y + y2 = 0 + 0.56

Combine like terms: 0 + 0.56 = 0.56
-1.32y + y2 = 0.56

The y term is -1.32y.  Take half its coefficient (-0.66).
