Solving for variable 'y'.

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

Divide each side by '2'.
15 + 6.5y + y2 = 0

Move the constant term to the right:

Add '-15' to each side of the equation.
15 + 6.5y + -15 + y2 = 0 + -15

Reorder the terms:
15 + -15 + 6.5y + y2 = 0 + -15

Combine like terms: 15 + -15 = 0
0 + 6.5y + y2 = 0 + -15
6.5y + y2 = 0 + -15

Combine like terms: 0 + -15 = -15
6.5y + y2 = -15

The y term is 6.5y.  Take half its coefficient (3.25).
