Solving for variable 'v'.

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

Divide each side by '5'.
-2.4 + -2v + v2 = 0

Move the constant term to the right:

Add '2.4' to each side of the equation.
-2.4 + -2v + 2.4 + v2 = 0 + 2.4

Reorder the terms:
-2.4 + 2.4 + -2v + v2 = 0 + 2.4

Combine like terms: -2.4 + 2.4 = 0.0
0.0 + -2v + v2 = 0 + 2.4
-2v + v2 = 0 + 2.4

Combine like terms: 0 + 2.4 = 2.4
-2v + v2 = 2.4

The v term is -2v.  Take half its coefficient (-1).
Square it (1) and add it to both sides.

Add '1' to each side of the equation.
-2v + 1 + v2 = 2.4 + 1

Reorder the terms:
1 + -2v + v2 = 2.4 + 1

Combine like terms: 2.4 + 1 = 3.4
1 + -2v + v2 = 3.4

Factor a perfect square on the left side:
(v + -1)(v + -1) = 3.4

Calculate the square root of the right side: 1.843908891

Break this problem into two subproblems by setting 
(v + -1) equal to 1.843908891 and -1.843908891.

Subproblem 1

v + -1 = 1.843908891 Simplifying v + -1 = 1.843908891 Reorder the terms: -1 + v = 1.843908891 Solving -1 + v = 1.843908891 Solving for variable 'v'. Move all terms containing v to the left, all other terms to the right. Add '1' to each side of the equation. -1 + 1 + v = 1.843908891 + 1 Combine like terms: -1 + 1 = 0 0 + v = 1.843908891 + 1 v = 1.843908891 + 1 Combine like terms: 1.843908891 + 1 = 2.843908891 v = 2.843908891 Simplifying v = 2.843908891

Subproblem 2

v + -1 = -1.843908891 Simplifying v + -1 = -1.843908891 Reorder the terms: -1 + v = -1.843908891 Solving -1 + v = -1.843908891 Solving for variable 'v'. Move all terms containing v to the left, all other terms to the right. Add '1' to each side of the equation. -1 + 1 + v = -1.843908891 + 1 Combine like terms: -1 + 1 = 0 0 + v = -1.843908891 + 1 v = -1.843908891 + 1 Combine like terms: -1.843908891 + 1 = -0.843908891 v = -0.843908891 Simplifying v = -0.843908891

Solution
