Solving
-6 + 12v + 5v2 = 0

Solving for variable 'v'.

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

Divide each side by '5'.
-1.2 + 2.4v + v2 = 0

Move the constant term to the right:

Add '1.2' to each side of the equation.
-1.2 + 2.4v + 1.2 + v2 = 0 + 1.2

Reorder the terms:
-1.2 + 1.2 + 2.4v + v2 = 0 + 1.2

Combine like terms: -1.2 + 1.2 = 0.0
0.0 + 2.4v + v2 = 0 + 1.2
2.4v + v2 = 0 + 1.2

Combine like terms: 0 + 1.2 = 1.2
2.4v + v2 = 1.2

The v term is 2.4v.  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.
2.4v + 1.44 + v2 = 1.2 + 1.44

Reorder the terms:
1.44 + 2.4v + v2 = 1.2 + 1.44

Combine like terms: 1.2 + 1.44 = 2.64
1.44 + 2.4v + v2 = 2.64

Factor a perfect square on the left side:
(v + 1.2)(v + 1.2) = 2.64

Calculate the square root of the right side: 1.624807681

Break this problem into two subproblems by setting 
(v + 1.2) equal to 1.624807681 and -1.624807681.

Subproblem 1

v + 1.2 = 1.624807681 Simplifying v + 1.2 = 1.624807681 Reorder the terms: 1.2 + v = 1.624807681 Solving 1.2 + v = 1.624807681 Solving for variable 'v'. Move all terms containing v to the left, all other terms to the right. Add '-1.2' to each side of the equation. 1.2 + -1.2 + v = 1.624807681 + -1.2 Combine like terms: 1.2 + -1.2 = 0.0 0.0 + v = 1.624807681 + -1.2 v = 1.624807681 + -1.2 Combine like terms: 1.624807681 + -1.2 = 0.424807681 v = 0.424807681 Simplifying v = 0.424807681

Subproblem 2

v + 1.2 = -1.624807681 Simplifying v + 1.2 = -1.624807681 Reorder the terms: 1.2 + v = -1.624807681 Solving 1.2 + v = -1.624807681 Solving for variable 'v'. Move all terms containing v to the left, all other terms to the right. Add '-1.2' to each side of the equation. 1.2 + -1.2 + v = -1.624807681 + -1.2 Combine like terms: 1.2 + -1.2 = 0.0 0.0 + v = -1.624807681 + -1.2 v = -1.624807681 + -1.2 Combine like terms: -1.624807681 + -1.2 = -2.824807681 v = -2.824807681 Simplifying v = -2.824807681

Solution
