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

Divide each side by '-4'.
-3.25 + -3.75y + y2 = 0

Move the constant term to the right:

Add '3.25' to each side of the equation.
-3.25 + -3.75y + 3.25 + y2 = 0 + 3.25

Reorder the terms:
-3.25 + 3.25 + -3.75y + y2 = 0 + 3.25

Combine like terms: -3.25 + 3.25 = 0.00
0.00 + -3.75y + y2 = 0 + 3.25
-3.75y + y2 = 0 + 3.25

Combine like terms: 0 + 3.25 = 3.25
-3.75y + y2 = 3.25

The y term is -3.75y.  Take half its coefficient (-1.875).
Square it (3.515625) and add it to both sides.

Add '3.515625' to each side of the equation.
-3.75y + 3.515625 + y2 = 3.25 + 3.515625

Reorder the terms:
3.515625 + -3.75y + y2 = 3.25 + 3.515625

Combine like terms: 3.25 + 3.515625 = 6.765625
3.515625 + -3.75y + y2 = 6.765625

Factor a perfect square on the left side:
(y + -1.875)(y + -1.875) = 6.765625

Calculate the square root of the right side: 2.601081506

Break this problem into two subproblems by setting

Simplifying
y + -1.875 = 2.601081506

Reorder the terms:
-1.875 + y = 2.601081506

Solving
-1.875 + y = 2.601081506

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Add '1.875' to each side of the equation.
-1.875 + 1.875 + y = 2.601081506 + 1.875

Combine like terms: -1.875 + 1.875 = 0.000
0.000 + y = 2.601081506 + 1.875
y = 2.601081506 + 1.875

Combine like terms: 2.601081506 + 1.875 = 4.476081506
y = 4.476081506
