0.36 + 0.6s + 0.25s2 = 0

Solving for variable 's'.

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

Divide each side by '0.25'.
1.44 + 2.4s + s2 = 0

Move the constant term to the right:

Add '-1.44' to each side of the equation.
1.44 + 2.4s + -1.44 + s2 = 0 + -1.44

Reorder the terms:
1.44 + -1.44 + 2.4s + s2 = 0 + -1.44

Combine like terms: 1.44 + -1.44 = 0.00
0.00 + 2.4s + s2 = 0 + -1.44
2.4s + s2 = 0 + -1.44

Combine like terms: 0 + -1.44 = -1.44
2.4s + s2 = -1.44

The s term is 2.4s.  Take half its coefficient (1.2).
Square it (1.44) and add it to both sides.

Add '1.44' to each side of the equation.
2.4s + 1.44 + s2 = -1.44 + 1.44

Reorder the terms:
1.44 + 2.4s + s2 = -1.44 + 1.44

Combine like terms: -1.44 + 1.44 = 0.00
1.44 + 2.4s + s2 = 0.00

Factor a perfect square on the left side:
(s + 1.2)(s + 1.2) = 0.00

Calculate the square root of the right side: 0.00

Break this problem into two subproblems by setting 
(s + 1.2) equal to 0.00 and 0.00.

Subproblem 1

s + 1.2 = 0.00 Simplifying s + 1.2 = 0.00 Reorder the terms: 1.2 + s = 0.00 Solving 1.2 + s = 0.00 Solving for variable 's'. Move all terms containing s to the left, all other terms to the right. Add '-1.2' to each side of the equation. 1.2 + -1.2 + s = 0.00 + -1.2 Combine like terms: 1.2 + -1.2 = 0.0 0.0 + s = 0.00 + -1.2 s = 0.00 + -1.2 Combine like terms: 0.00 + -1.2 = -1.2 s = -1.2 Simplifying s = -1.2

Subproblem 2

s + 1.2 = 0.00 Simplifying s + 1.2 = 0.00 Reorder the terms: 1.2 + s = 0.00 Solving 1.2 + s = 0.00 Solving for variable 's'. Move all terms containing s to the left, all other terms to the right. Add '-1.2' to each side of the equation. 1.2 + -1.2 + s = 0.00 + -1.2 Combine like terms: 1.2 + -1.2 = 0.0 0.0 + s = 0.00 + -1.2 s = 0.00 + -1.2 Combine like terms: 0.00 + -1.2 = -1.2 s = -1.2 Simplifying s = -1.2

Solution

The solution to the problem is based on the solutions from the subproblems. s = {-1.2, -1.2}
