Solving for variable 'y'.

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

Divide each side by '2'.
4.5 + (4y3) + y6 = 0

Move the constant term to the right:

Add '-4.5' to each side of the equation.
4.5 + (4y3) + -4.5 + y6 = 0 + -4.5

Reorder the terms:
4.5 + -4.5 + (4y3) + y6 = 0 + -4.5

Combine like terms: 4.5 + -4.5 = 0.0
