35 + -44v + 10v2 = 0

Solving for variable 'v'.

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

Divide each side by '10'.
3.5 + -4.4v + v2 = 0

Move the constant term to the right:

Add '-3.5' to each side of the equation.
3.5 + -4.4v + -3.5 + v2 = 0 + -3.5

Reorder the terms:
3.5 + -3.5 + -4.4v + v2 = 0 + -3.5

Combine like terms: 3.5 + -3.5 = 0.0
0.0 + -4.4v + v2 = 0 + -3.5
-4.4v + v2 = 0 + -3.5

Combine like terms: 0 + -3.5 = -3.5
-4.4v + v2 = -3.5

The v term is -4.4v.  Take half its coefficient (-2.2).
Square it (4.84) and add it to both sides.

Add '4.84' to each side of the equation.
-4.4v + 4.84 + v2 = -3.5 + 4.84

Reorder the terms:
4.84 + -4.4v + v2 = -3.5 + 4.84

Combine like terms: -3.5 + 4.84 = 1.34
4.84 + -4.4v + v2 = 1.34

Factor a perfect square on the left side:
(v + -2.2)(v + -2.2) = 1.34

Calculate the square root of the right side: 1.15758369

Break this problem into two subproblems by setting 
(v + -2.2) equal to 1.15758369 and -1.15758369.

Subproblem 1

v + -2.2 = 1.15758369 Simplifying v + -2.2 = 1.15758369 Reorder the terms: -2.2 + v = 1.15758369 Solving -2.2 + v = 1.15758369 Solving for variable 'v'. Move all terms containing v to the left, all other terms to the right. Add '2.2' to each side of the equation. -2.2 + 2.2 + v = 1.15758369 + 2.2 Combine like terms: -2.2 + 2.2 = 0.0 0.0 + v = 1.15758369 + 2.2 v = 1.15758369 + 2.2 Combine like terms: 1.15758369 + 2.2 = 3.35758369 v = 3.35758369 Simplifying v = 3.35758369

Subproblem 2

v + -2.2 = -1.15758369 Simplifying v + -2.2 = -1.15758369 Reorder the terms: -2.2 + v = -1.15758369 Solving -2.2 + v = -1.15758369 Solving for variable 'v'. Move all terms containing v to the left, all other terms to the right. Add '2.2' to each side of the equation. -2.2 + 2.2 + v = -1.15758369 + 2.2 Combine like terms: -2.2 + 2.2 = 0.0 0.0 + v = -1.15758369 + 2.2 v = -1.15758369 + 2.2 Combine like terms: -1.15758369 + 2.2 = 1.04241631 v = 1.04241631 Simplifying v = 1.04241631
