Simplifying v2 + 3v + -128 = 0 Reorder the terms: -128 + 3v + v2 = 0 Solving -128 + 3v + v2 = 0 Solving for variable 'v'. Begin completing the square. Move the constant term to the right: Add '128' to each side of the equation. -128 + 3v + 128 + v2 = 0 + 128 Reorder the terms: -128 + 128 + 3v + v2 = 0 + 128 Combine like terms: -128 + 128 = 0 0 + 3v + v2 = 0 + 128 3v + v2 = 0 + 128 Combine like terms: 0 + 128 = 128 3v + v2 = 128 The v term is 3v. Take half its coefficient (1.5). Square it (2.25) and add it to both sides. Add '2.25' to each side of the equation. 3v + 2.25 + v2 = 128 + 2.25 Reorder the terms: 2.25 + 3v + v2 = 128 + 2.25 Combine like terms: 128 + 2.25 = 130.25 2.25 + 3v + v2 = 130.25 Factor a perfect square on the left side: (v + 1.5)(v + 1.5) = 130.25 Calculate the square root of the right side: 11.412712211 Break this problem into two subproblems by setting (v + 1.5) equal to 11.412712211 and -11.412712211.Subproblem 1
v + 1.5 = 11.412712211 Simplifying v + 1.5 = 11.412712211 Reorder the terms: 1.5 + v = 11.412712211 Solving 1.5 + v = 11.412712211 Solving for variable 'v'. Move all terms containing v to the left, all other terms to the right. Add '-1.5' to each side of the equation. 1.5 + -1.5 + v = 11.412712211 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + v = 11.412712211 + -1.5 v = 11.412712211 + -1.5 Combine like terms: 11.412712211 + -1.5 = 9.912712211 v = 9.912712211 Simplifying v = 9.912712211Subproblem 2
v + 1.5 = -11.412712211 Simplifying v + 1.5 = -11.412712211 Reorder the terms: 1.5 + v = -11.412712211 Solving 1.5 + v = -11.412712211 Solving for variable 'v'. Move all terms containing v to the left, all other terms to the right. Add '-1.5' to each side of the equation. 1.5 + -1.5 + v = -11.412712211 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + v = -11.412712211 + -1.5 v = -11.412712211 + -1.5 Combine like terms: -11.412712211 + -1.5 = -12.912712211 v = -12.912712211 Simplifying v = -12.912712211Solution
The solution to the problem is based on the solutions from the subproblems. v = {9.912712211, -12.912712211}
