Divide each side by '49.05'.
-1 + 0.02038735984v + v2 = 0

Move the constant term to the right:

Add '1' to each side of the equation.
-1 + 0.02038735984v + 1 + v2 = 0 + 1

Reorder the terms:
-1 + 1 + 0.02038735984v + v2 = 0 + 1

Combine like terms: -1 + 1 = 0
0 + 0.02038735984v + v2 = 0 + 1
0.02038735984v + v2 = 0 + 1

Combine like terms: 0 + 1 = 1
0.02038735984v + v2 = 1

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.
0.02038735984v + 0.25 + v2 = 1 + 0.25

Reorder the terms:
0.25 + 0.02038735984v + v2 = 1 + 0.25

Combine like terms: 1 + 0.25 = 1.25
0.25 + 0.02038735984v + v2 = 1.25

Break this problem into two subproblems by setting 
(v + 0.5) equal to 1.118033989 and -1.118033989.

Subproblem 1

v + 0.5 = 1.118033989 Simplifying v + 0.5 = 1.118033989 Reorder the terms: 0.5 + v = 1.118033989 Solving 0.5 + v = 1.118033989 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 = 1.118033989 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + v = 1.118033989 + -0.5 v = 1.118033989 + -0.5 Combine like terms: 1.118033989 + -0.5 = 0.618033989 v = 0.618033989 Simplifying v = 0.618033989

Subproblem 2

v + 0.5 = -1.118033989 Simplifying v + 0.5 = -1.118033989 Reorder the terms: 0.5 + v = -1.118033989 Solving 0.5 + v = -1.118033989 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 = -1.118033989 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + v = -1.118033989 + -0.5 v = -1.118033989 + -0.5 Combine like terms: -1.118033989 + -0.5 = -1.618033989 v = -1.618033989 Simplifying v = -1.618033989

Solution
