5 + -1y + 5y2 = 0

Solving for variable 'y'.

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

Divide each side by '5'.
1 + -0.2y + y2 = 0

Move the constant term to the right:

Add '-1' to each side of the equation.
1 + -0.2y + -1 + y2 = 0 + -1

Reorder the terms:
1 + -1 + -0.2y + y2 = 0 + -1

Combine like terms: 1 + -1 = 0
0 + -0.2y + y2 = 0 + -1
-0.2y + y2 = 0 + -1

Combine like terms: 0 + -1 = -1
-0.2y + y2 = -1

The y term is -0.2y.  Take half its coefficient (-0.1).
Square it (0.01) and add it to both sides.

Add '0.01' to each side of the equation.
-0.2y + 0.01 + y2 = -1 + 0.01

Reorder the terms:
0.01 + -0.2y + y2 = -1 + 0.01

Combine like terms: -1 + 0.01 = -0.99
0.01 + -0.2y + y2 = -0.99

Factor a perfect square on the left side:
(y + -0.1)(y + -0.1) = -0.99

Can't calculate square root of the right side.

The solution to this equation could not be determined.
