Solving for variable 's'.

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

Divide each side by '5'.
-2.4 + 0.2s + s2 = 0

Move the constant term to the right:

Add '2.4' to each side of the equation.
-2.4 + 0.2s + 2.4 + s2 = 0 + 2.4

Reorder the terms:
-2.4 + 2.4 + 0.2s + s2 = 0 + 2.4

Combine like terms: -2.4 + 2.4 = 0.0
0.0 + 0.2s + s2 = 0 + 2.4
0.2s + s2 = 0 + 2.4

Combine like terms: 0 + 2.4 = 2.4
0.2s + s2 = 2.4

The s term is 0.2s.  Take half its coefficient (0.1).
Square it (0.01) and add it to both sides.

Add '0.01' to each side of the equation.
0.2s + 0.01 + s2 = 2.4 + 0.01

Reorder the terms:
0.01 + 0.2s + s2 = 2.4 + 0.01

Combine like terms: 2.4 + 0.01 = 2.41
0.01 + 0.2s + s2 = 2.41

Factor a perfect square on the left side:
(s + 0.1)(s + 0.1) = 2.41

Calculate the square root of the right side: 1.55241747

Break this problem into two subproblems by setting 
(s + 0.1) equal to 1.55241747 and -1.55241747.

Subproblem 1

s + 0.1 = 1.55241747 Simplifying s + 0.1 = 1.55241747 Reorder the terms: 0.1 + s = 1.55241747 Solving 0.1 + s = 1.55241747 Solving for variable 's'. Move all terms containing s to the left, all other terms to the right. Add '-0.1' to each side of the equation. 0.1 + -0.1 + s = 1.55241747 + -0.1 Combine like terms: 0.1 + -0.1 = 0.0 0.0 + s = 1.55241747 + -0.1 s = 1.55241747 + -0.1 Combine like terms: 1.55241747 + -0.1 = 1.45241747 s = 1.45241747 Simplifying s = 1.45241747

Subproblem 2

s + 0.1 = -1.55241747 Simplifying s + 0.1 = -1.55241747 Reorder the terms: 0.1 + s = -1.55241747 Solving 0.1 + s = -1.55241747 Solving for variable 's'. Move all terms containing s to the left, all other terms to the right. Add '-0.1' to each side of the equation. 0.1 + -0.1 + s = -1.55241747 + -0.1 Combine like terms: 0.1 + -0.1 = 0.0 0.0 + s = -1.55241747 + -0.1 s = -1.55241747 + -0.1 Combine like terms: -1.55241747 + -0.1 = -1.65241747 s = -1.65241747 Simplifying s = -1.65241747

Solution
