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

Divide each side by '2'.
-0.5 + 1.5y + y2 = 0

Move the constant term to the right:

Add '0.5' to each side of the equation.
-0.5 + 1.5y + 0.5 + y2 = 0 + 0.5

Reorder the terms:
-0.5 + 0.5 + 1.5y + y2 = 0 + 0.5

Combine like terms: -0.5 + 0.5 = 0.0
0.0 + 1.5y + y2 = 0 + 0.5
1.5y + y2 = 0 + 0.5

Combine like terms: 0 + 0.5 = 0.5
1.5y + y2 = 0.5

The y term is 1.5y.  Take half its coefficient (0.75).
Square it (0.5625) and add it to both sides.

Add '0.5625' to each side of the equation.
1.5y + 0.5625 + y2 = 0.5 + 0.5625

Reorder the terms:
0.5625 + 1.5y + y2 = 0.5 + 0.5625

Combine like terms: 0.5 + 0.5625 = 1.0625
0.5625 + 1.5y + y2 = 1.0625
