Solving for variable 's'.

Begin completing the square.  Divide all terms by
0.0000000002 the coefficient of the squared term: 

Divide each side by '0.0000000002'.
-20000000000 + 5s + s2 = 0

Move the constant term to the right:

Add '20000000000' to each side of the equation.
-20000000000 + 5s + 20000000000 + s2 = 0 + 20000000000

Reorder the terms:
-20000000000 + 20000000000 + 5s + s2 = 0 + 20000000000

Combine like terms: -20000000000 + 20000000000 = 0
0 + 5s + s2 = 0 + 20000000000
5s + s2 = 0 + 20000000000

Combine like terms: 0 + 20000000000 = 20000000000
5s + s2 = 20000000000

The s term is 5s.  Take half its coefficient (2.5).
Square it (6.25) and add it to both sides.

Add '6.25' to each side of the equation.
5s + 6.25 + s2 = 20000000000 + 6.25

Reorder the terms:
6.25 + 5s + s2 = 20000000000 + 6.25

Combine like terms: 20000000000 + 6.25 = 20000000006.25
6.25 + 5s + s2 = 20000000006.25

Factor a perfect square on the left side:
(s + 2.5)(s + 2.5) = 20000000006.25
