Solving for variable 's'.

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

Divide each side by '4'.
-1.5 + 0.75s + s2 = 0

Move the constant term to the right:

Add '1.5' to each side of the equation.
-1.5 + 0.75s + 1.5 + s2 = 0 + 1.5

Reorder the terms:
-1.5 + 1.5 + 0.75s + s2 = 0 + 1.5

Combine like terms: -1.5 + 1.5 = 0.0
0.0 + 0.75s + s2 = 0 + 1.5
0.75s + s2 = 0 + 1.5

Combine like terms: 0 + 1.5 = 1.5
0.75s + s2 = 1.5

The s term is 0.75s.  Take half its coefficient (0.375).
Square it (0.140625) and add it to both sides.

Add '0.140625' to each side of the equation.
0.75s + 0.140625 + s2 = 1.5 + 0.140625

Reorder the terms:
0.140625 + 0.75s + s2 = 1.5 + 0.140625

Combine like terms: 1.5 + 0.140625 = 1.640625
0.140625 + 0.75s + s2 = 1.640625

Factor a perfect square on the left side:
(s + 0.375)(s + 0.375) = 1.640625

Calculate the square root of the right side: 1.280868846
