Solving for variable 'y'.

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

Divide each side by '5'.
0.2 + -1.4y + y2 = 0

Move the constant term to the right:

Add '-0.2' to each side of the equation.
0.2 + -1.4y + -0.2 + y2 = 0 + -0.2

Reorder the terms:
0.2 + -0.2 + -1.4y + y2 = 0 + -0.2

Combine like terms: 0.2 + -0.2 = 0.0
0.0 + -1.4y + y2 = 0 + -0.2
-1.4y + y2 = 0 + -0.2

Combine like terms: 0 + -0.2 = -0.2
-1.4y + y2 = -0.2

The y term is -1.4y.  Take half its coefficient (-0.7).
Square it (0.49) and add it to both sides.

Add '0.49' to each side of the equation.
-1.4y + 0.49 + y2 = -0.2 + 0.49

Reorder the terms:
0.49 + -1.4y + y2 = -0.2 + 0.49

Combine like terms: -0.2 + 0.49 = 0.29
0.49 + -1.4y + y2 = 0.29

Factor a perfect square on the left side:
(y + -0.7)(y + -0.7) = 0.29

Calculate the square root of the right side: 0.538516481

Break this problem into two subproblems by setting 
(y + -0.7) equal to 0.538516481 and -0.538516481.
