Solving
13 + -10v + 4v2 = -1

Solving for variable 'v'.

Reorder the terms:
13 + 1 + -10v + 4v2 = -1 + 1

Combine like terms: 13 + 1 = 14
14 + -10v + 4v2 = -1 + 1

Combine like terms: -1 + 1 = 0
14 + -10v + 4v2 = 0

Factor out the Greatest Common Factor (GCF), '2'.
2(7 + -5v + 2v2) = 0

Ignore the factor 2.

Subproblem 1
Set the factor '(7 + -5v + 2v2)' equal to zero and attempt to solve:

Simplifying
7 + -5v + 2v2 = 0

Solving
7 + -5v + 2v2 = 0

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

Divide each side by '2'.
3.5 + -2.5v + v2 = 0

Move the constant term to the right:

Add '-3.5' to each side of the equation.
3.5 + -2.5v + -3.5 + v2 = 0 + -3.5

Reorder the terms:
3.5 + -3.5 + -2.5v + v2 = 0 + -3.5

Combine like terms: 3.5 + -3.5 = 0.0
0.0 + -2.5v + v2 = 0 + -3.5
-2.5v + v2 = 0 + -3.5

Combine like terms: 0 + -3.5 = -3.5
-2.5v + v2 = -3.5

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 = -3.5 + 1.5625

Reorder the terms:
1.5625 + -2.5v + v2 = -3.5 + 1.5625

Combine like terms: -3.5 + 1.5625 = -1.9375
1.5625 + -2.5v + v2 = -1.9375

Factor a perfect square on the left side:
(v + -1.25)(v + -1.25) = -1.9375

Can't calculate square root of the right side.
