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

Divide each side by '8'.
1.25 + -1.625y + y2 = 0

Move the constant term to the right:

Add '-1.25' to each side of the equation.
1.25 + -1.625y + -1.25 + y2 = 0 + -1.25

Reorder the terms:
1.25 + -1.25 + -1.625y + y2 = 0 + -1.25

Combine like terms: 1.25 + -1.25 = 0.00
0.00 + -1.625y + y2 = 0 + -1.25
-1.625y + y2 = 0 + -1.25

Combine like terms: 0 + -1.25 = -1.25
-1.625y + y2 = -1.25

The y term is -1.625y.  Take half its coefficient (-0.8125).
Square it (0.66015625) and add it to both sides.
