Solving for variable 'y'.

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

Divide each side by '0.02'.
-1 + -0.5y + y2 = 0

Move the constant term to the right:

Add '1' to each side of the equation.
-1 + -0.5y + 1 + y2 = 0 + 1

Reorder the terms:
-1 + 1 + -0.5y + y2 = 0 + 1

Combine like terms: -1 + 1 = 0
0 + -0.5y + y2 = 0 + 1
-0.5y + y2 = 0 + 1

Combine like terms: 0 + 1 = 1
-0.5y + y2 = 1

The y term is -0.5y.  Take half its coefficient (-0.25).
Square it (0.0625) and add it to both sides.

Add '0.0625' to each side of the equation.
-0.5y + 0.0625 + y2 = 1 + 0.0625

Reorder the terms:
0.0625 + -0.5y + y2 = 1 + 0.0625

Combine like terms: 1 + 0.0625 = 1.0625
0.0625 + -0.5y + y2 = 1.0625

Factor a perfect square on the left side:
(y + -0.25)(y + -0.25) = 1.0625
