Solving
16 + -4v + v2 = 0

Solving for variable 'v'.

Begin completing the square.

Move the constant term to the right:

Add '-16' to each side of the equation.
16 + -4v + -16 + v2 = 0 + -16

Reorder the terms:
16 + -16 + -4v + v2 = 0 + -16

Combine like terms: 16 + -16 = 0
0 + -4v + v2 = 0 + -16
-4v + v2 = 0 + -16

Combine like terms: 0 + -16 = -16
-4v + v2 = -16

The v term is -4v.  Take half its coefficient (-2).
Square it (4) and add it to both sides.

Add '4' to each side of the equation.
-4v + 4 + v2 = -16 + 4

Reorder the terms:
4 + -4v + v2 = -16 + 4

Combine like terms: -16 + 4 = -12
4 + -4v + v2 = -12

Factor a perfect square on the left side:
(v + -2)(v + -2) = -12

Can't calculate square root of the right side.
