Solving
-41 + -30v + v2 = 0

Solving for variable 'v'.

Begin completing the square.

Move the constant term to the right:

Add '41' to each side of the equation.
-41 + -30v + 41 + v2 = 0 + 41

Reorder the terms:
-41 + 41 + -30v + v2 = 0 + 41

Combine like terms: -41 + 41 = 0
0 + -30v + v2 = 0 + 41
-30v + v2 = 0 + 41

Combine like terms: 0 + 41 = 41
-30v + v2 = 41

The v term is -30v.  Take half its coefficient (-15).
Square it (225) and add it to both sides.

Add '225' to each side of the equation.
-30v + 225 + v2 = 41 + 225

Reorder the terms:
225 + -30v + v2 = 41 + 225

Combine like terms: 41 + 225 = 266
225 + -30v + v2 = 266

Factor a perfect square on the left side:
(v + -15)(v + -15) = 266
