Solving for variable 'y'.

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

Divide each side by '2'.
1.5 + 106y + y2 = 0

Move the constant term to the right:

Add '-1.5' to each side of the equation.
1.5 + 106y + -1.5 + y2 = 0 + -1.5

Reorder the terms:
1.5 + -1.5 + 106y + y2 = 0 + -1.5

Combine like terms: 1.5 + -1.5 = 0.0
0.0 + 106y + y2 = 0 + -1.5
106y + y2 = 0 + -1.5

Combine like terms: 0 + -1.5 = -1.5
106y + y2 = -1.5

The y term is 106y.  Take half its coefficient (53).
Square it (2809) and add it to both sides.

Add '2809' to each side of the equation.
106y + 2809 + y2 = -1.5 + 2809

Reorder the terms:
2809 + 106y + y2 = -1.5 + 2809

Combine like terms: -1.5 + 2809 = 2807.5
2809 + 106y + y2 = 2807.5

Factor a perfect square on the left side:
(y + 53)(y + 53) = 2807.5

Calculate the square root of the right side: 52.985847167
