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

Divide each side by '2'.
3.5 + -2y + y2 = 0

Move the constant term to the right:

Add '-3.5' to each side of the equation.
3.5 + -2y + -3.5 + y2 = 0 + -3.5

Reorder the terms:
3.5 + -3.5 + -2y + y2 = 0 + -3.5

Combine like terms: 3.5 + -3.5 = 0.0
0.0 + -2y + y2 = 0 + -3.5
-2y + y2 = 0 + -3.5

Combine like terms: 0 + -3.5 = -3.5
-2y + y2 = -3.5

The y term is -2y.  Take half its coefficient (-1).
Square it (1) and add it to both sides.

Add '1' to each side of the equation.
-2y + 1 + y2 = -3.5 + 1
