Solving for variable 'v'.

Begin completing the square.  Divide all terms by
-2 the coefficient of the squared term: 

Divide each side by '-2'.
-2 + -2.5v + v2 = 0

Move the constant term to the right:

Add '2' to each side of the equation.
-2 + -2.5v + 2 + v2 = 0 + 2

Reorder the terms:
-2 + 2 + -2.5v + v2 = 0 + 2

Combine like terms: -2 + 2 = 0
0 + -2.5v + v2 = 0 + 2
-2.5v + v2 = 0 + 2

Combine like terms: 0 + 2 = 2
-2.5v + v2 = 2

The v term is -2.5v.  Take half its coefficient (-1.25).
Square it (1.5625) and add it to both sides.

Add '1.5625' to each side of the equation.
-2.5v + 1.5625 + v2 = 2 + 1.5625

Reorder the terms:
1.5625 + -2.5v + v2 = 2 + 1.5625

Combine like terms: 2 + 1.5625 = 3.5625
1.5625 + -2.5v + v2 = 3.5625

Factor a perfect square on the left side:
(v + -1.25)(v + -1.25) = 3.5625

Calculate the square root of the right side: 1.887458609

Break this problem into two subproblems by setting 
(v + -1.25) equal to 1.887458609 and -1.887458609.

Subproblem 1

v + -1.25 = 1.887458609 Simplifying v + -1.25 = 1.887458609 Reorder the terms: -1.25 + v = 1.887458609 Solving -1.25 + v = 1.887458609 Solving for variable 'v'. Move all terms containing v to the left, all other terms to the right. Add '1.25' to each side of the equation. -1.25 + 1.25 + v = 1.887458609 + 1.25 Combine like terms: -1.25 + 1.25 = 0.00 0.00 + v = 1.887458609 + 1.25 v = 1.887458609 + 1.25 Combine like terms: 1.887458609 + 1.25 = 3.137458609 v = 3.137458609 Simplifying v = 3.137458609

Subproblem 2

v + -1.25 = -1.887458609 Simplifying v + -1.25 = -1.887458609 Reorder the terms: -1.25 + v = -1.887458609 Solving -1.25 + v = -1.887458609 Solving for variable 'v'. Move all terms containing v to the left, all other terms to the right. Add '1.25' to each side of the equation. -1.25 + 1.25 + v = -1.887458609 + 1.25 Combine like terms: -1.25 + 1.25 = 0.00 0.00 + v = -1.887458609 + 1.25 v = -1.887458609 + 1.25 Combine like terms: -1.887458609 + 1.25 = -0.637458609 v = -0.637458609 Simplifying v = -0.637458609
