Solving for variable 's'.

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

Divide each side by '2'.
102 + -3.5s + s2 = 0

Move the constant term to the right:

Add '-102' to each side of the equation.
102 + -3.5s + -102 + s2 = 0 + -102

Reorder the terms:
102 + -102 + -3.5s + s2 = 0 + -102

Combine like terms: 102 + -102 = 0
0 + -3.5s + s2 = 0 + -102
-3.5s + s2 = 0 + -102

Combine like terms: 0 + -102 = -102
-3.5s + s2 = -102

The s term is -3.5s.  Take half its coefficient (-1.75).
Square it (3.0625) and add it to both sides.

Add '3.0625' to each side of the equation.
-3.5s + 3.0625 + s2 = -102 + 3.0625

Reorder the terms:
3.0625 + -3.5s + s2 = -102 + 3.0625

Combine like terms: -102 + 3.0625 = -98.9375
3.0625 + -3.5s + s2 = -98.9375

Factor a perfect square on the left side:
(s + -1.75)(s + -1.75) = -98.9375

Can't calculate square root of the right side.
