Solving for variable 'y'.

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

Divide each side by '4'.
3.75 + -2.75y + y2 = 0

Move the constant term to the right:

Add '-3.75' to each side of the equation.
3.75 + -2.75y + -3.75 + y2 = 0 + -3.75

Reorder the terms:
3.75 + -3.75 + -2.75y + y2 = 0 + -3.75

Combine like terms: 3.75 + -3.75 = 0.00
0.00 + -2.75y + y2 = 0 + -3.75
-2.75y + y2 = 0 + -3.75

Combine like terms: 0 + -3.75 = -3.75
-2.75y + y2 = -3.75

The y term is -2.75y.  Take half its coefficient (-1.375).
Square it (1.890625) and add it to both sides.

Add '1.890625' to each side of the equation.
-2.75y + 1.890625 + y2 = -3.75 + 1.890625
