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

Divide each side by '2'.
-7.5 + v + v2 = 0

Move the constant term to the right:

Add '7.5' to each side of the equation.
-7.5 + v + 7.5 + v2 = 0 + 7.5

Reorder the terms:
-7.5 + 7.5 + v + v2 = 0 + 7.5

Combine like terms: -7.5 + 7.5 = 0.0
0.0 + v + v2 = 0 + 7.5
v + v2 = 0 + 7.5

Combine like terms: 0 + 7.5 = 7.5
v + v2 = 7.5

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 = 7.5 + 0.25

Combine like terms:  + 0.25 = 1.25
1.25 + v2 = 7.5 + 0.25

Combine like terms: 7.5 + 0.25 = 7.75
1.25 + v2 = 7.75

Factor a perfect square on the left side:
(v + 0.5)(v + 0.5) = 7.75

Calculate the square root of the right side: 2.783882181

Break this problem into two subproblems by setting 
(v + 0.5) equal to 2.783882181 and -2.783882181.

Subproblem 1

v + 0.5 = 2.783882181 Simplifying v + 0.5 = 2.783882181 Reorder the terms: 0.5 + v = 2.783882181 Solving 0.5 + v = 2.783882181 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 = 2.783882181 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + v = 2.783882181 + -0.5 v = 2.783882181 + -0.5 Combine like terms: 2.783882181 + -0.5 = 2.283882181 v = 2.283882181 Simplifying v = 2.283882181

Subproblem 2

v + 0.5 = -2.783882181 Simplifying v + 0.5 = -2.783882181 Reorder the terms: 0.5 + v = -2.783882181 Solving 0.5 + v = -2.783882181 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 = -2.783882181 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + v = -2.783882181 + -0.5 v = -2.783882181 + -0.5 Combine like terms: -2.783882181 + -0.5 = -3.283882181 v = -3.283882181 Simplifying v = -3.283882181

Solution
