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

Divide each side by '5'.
-4.4 + v + v2 = 0

Move the constant term to the right:

Add '4.4' to each side of the equation.
-4.4 + v + 4.4 + v2 = 0 + 4.4

Reorder the terms:
-4.4 + 4.4 + v + v2 = 0 + 4.4

Combine like terms: -4.4 + 4.4 = 0.0
0.0 + v + v2 = 0 + 4.4
v + v2 = 0 + 4.4

Combine like terms: 0 + 4.4 = 4.4
v + v2 = 4.4

The v term is v.  Take half its coefficient (0.5).
Square it (0.25) and add it to both sides.

Add '0.25' to each side of the equation.
 + 0.25 + v2 = 4.4 + 0.25

Combine like terms:  + 0.25 = 1.25
1.25 + v2 = 4.4 + 0.25

Combine like terms: 4.4 + 0.25 = 4.65
1.25 + v2 = 4.65

Factor a perfect square on the left side:
(v + 0.5)(v + 0.5) = 4.65

Calculate the square root of the right side: 2.156385865

Break this problem into two subproblems by setting 
(v + 0.5) equal to 2.156385865 and -2.156385865.

Subproblem 1

v + 0.5 = 2.156385865 Simplifying v + 0.5 = 2.156385865 Reorder the terms: 0.5 + v = 2.156385865 Solving 0.5 + v = 2.156385865 Solving for variable 'v'. Move all terms containing v to the left, all other terms to the right. Add '-0.5' to each side of the equation. 0.5 + -0.5 + v = 2.156385865 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + v = 2.156385865 + -0.5 v = 2.156385865 + -0.5 Combine like terms: 2.156385865 + -0.5 = 1.656385865 v = 1.656385865 Simplifying v = 1.656385865

Subproblem 2

v + 0.5 = -2.156385865 Simplifying v + 0.5 = -2.156385865 Reorder the terms: 0.5 + v = -2.156385865 Solving 0.5 + v = -2.156385865 Solving for variable 'v'. Move all terms containing v to the left, all other terms to the right. Add '-0.5' to each side of the equation. 0.5 + -0.5 + v = -2.156385865 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + v = -2.156385865 + -0.5 v = -2.156385865 + -0.5 Combine like terms: -2.156385865 + -0.5 = -2.656385865 v = -2.656385865 Simplifying v = -2.656385865
