Solving for variable 'v'.

Begin completing the square.

Move the constant term to the right:

Add '-11' to each side of the equation.
11 + -7v + -11 + v2 = 0 + -11

Reorder the terms:
11 + -11 + -7v + v2 = 0 + -11

Combine like terms: 11 + -11 = 0
0 + -7v + v2 = 0 + -11
-7v + v2 = 0 + -11

Combine like terms: 0 + -11 = -11
-7v + v2 = -11

The v term is -7v.  Take half its coefficient (-3.5).
Square it (12.25) and add it to both sides.

Add '12.25' to each side of the equation.
-7v + 12.25 + v2 = -11 + 12.25

Reorder the terms:
12.25 + -7v + v2 = -11 + 12.25

Combine like terms: -11 + 12.25 = 1.25
12.25 + -7v + v2 = 1.25

Factor a perfect square on the left side:
(v + -3.5)(v + -3.5) = 1.25
