150 + -1.2v + -0.04v2 = -150 + 150 + 1.2v + -1.2v + 0.04v2 + -0.04v2

Combine like terms: -150 + 150 = 0
150 + -1.2v + -0.04v2 = 0 + 1.2v + -1.2v + 0.04v2 + -0.04v2
150 + -1.2v + -0.04v2 = 1.2v + -1.2v + 0.04v2 + -0.04v2

Combine like terms: 1.2v + -1.2v = 0.0
150 + -1.2v + -0.04v2 = 0.0 + 0.04v2 + -0.04v2
150 + -1.2v + -0.04v2 = 0.04v2 + -0.04v2

Combine like terms: 0.04v2 + -0.04v2 = 0.00
150 + -1.2v + -0.04v2 = 0.00

Begin completing the square.  Divide all terms by
-0.04 the coefficient of the squared term: 

Divide each side by '-0.04'.
-3750 + 30v + v2 = 0

Move the constant term to the right:

Add '3750' to each side of the equation.
-3750 + 30v + 3750 + v2 = 0 + 3750

Reorder the terms:
-3750 + 3750 + 30v + v2 = 0 + 3750

Combine like terms: -3750 + 3750 = 0
0 + 30v + v2 = 0 + 3750
30v + v2 = 0 + 3750

Combine like terms: 0 + 3750 = 3750
30v + v2 = 3750

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 = 3750 + 225

Reorder the terms:
225 + 30v + v2 = 3750 + 225

Combine like terms: 3750 + 225 = 3975
225 + 30v + v2 = 3975

Factor a perfect square on the left side:
(v + 15)(v + 15) = 3975

Calculate the square root of the right side: 63.047601065

Break this problem into two subproblems by setting 
(v + 15) equal to 63.047601065 and -63.047601065.

Subproblem 1

v + 15 = 63.047601065 Simplifying v + 15 = 63.047601065 Reorder the terms: 15 + v = 63.047601065 Solving 15 + v = 63.047601065 Solving for variable 'v'. Move all terms containing v to the left, all other terms to the right. Add '-15' to each side of the equation. 15 + -15 + v = 63.047601065 + -15 Combine like terms: 15 + -15 = 0 0 + v = 63.047601065 + -15 v = 63.047601065 + -15 Combine like terms: 63.047601065 + -15 = 48.047601065 v = 48.047601065 Simplifying v = 48.047601065

Subproblem 2

v + 15 = -63.047601065 Simplifying v + 15 = -63.047601065 Reorder the terms: 15 + v = -63.047601065 Solving 15 + v = -63.047601065 Solving for variable 'v'. Move all terms containing v to the left, all other terms to the right. Add '-15' to each side of the equation. 15 + -15 + v = -63.047601065 + -15 Combine like terms: 15 + -15 = 0 0 + v = -63.047601065 + -15 v = -63.047601065 + -15 Combine like terms: -63.047601065 + -15 = -78.047601065 v = -78.047601065 Simplifying v = -78.047601065
