Simplifying v2 + 27v + 75 = 0 Reorder the terms: 75 + 27v + v2 = 0 Solving 75 + 27v + v2 = 0 Solving for variable 'v'. Begin completing the square. Move the constant term to the right: Add '-75' to each side of the equation. 75 + 27v + -75 + v2 = 0 + -75 Reorder the terms: 75 + -75 + 27v + v2 = 0 + -75 Combine like terms: 75 + -75 = 0 0 + 27v + v2 = 0 + -75 27v + v2 = 0 + -75 Combine like terms: 0 + -75 = -75 27v + v2 = -75 The v term is 27v. Take half its coefficient (13.5). Square it (182.25) and add it to both sides. Add '182.25' to each side of the equation. 27v + 182.25 + v2 = -75 + 182.25 Reorder the terms: 182.25 + 27v + v2 = -75 + 182.25 Combine like terms: -75 + 182.25 = 107.25 182.25 + 27v + v2 = 107.25 Factor a perfect square on the left side: (v + 13.5)(v + 13.5) = 107.25 Calculate the square root of the right side: 10.356157589 Break this problem into two subproblems by setting (v + 13.5) equal to 10.356157589 and -10.356157589.Subproblem 1
v + 13.5 = 10.356157589 Simplifying v + 13.5 = 10.356157589 Reorder the terms: 13.5 + v = 10.356157589 Solving 13.5 + v = 10.356157589 Solving for variable 'v'. Move all terms containing v to the left, all other terms to the right. Add '-13.5' to each side of the equation. 13.5 + -13.5 + v = 10.356157589 + -13.5 Combine like terms: 13.5 + -13.5 = 0.0 0.0 + v = 10.356157589 + -13.5 v = 10.356157589 + -13.5 Combine like terms: 10.356157589 + -13.5 = -3.143842411 v = -3.143842411 Simplifying v = -3.143842411Subproblem 2
v + 13.5 = -10.356157589 Simplifying v + 13.5 = -10.356157589 Reorder the terms: 13.5 + v = -10.356157589 Solving 13.5 + v = -10.356157589 Solving for variable 'v'. Move all terms containing v to the left, all other terms to the right. Add '-13.5' to each side of the equation. 13.5 + -13.5 + v = -10.356157589 + -13.5 Combine like terms: 13.5 + -13.5 = 0.0 0.0 + v = -10.356157589 + -13.5 v = -10.356157589 + -13.5 Combine like terms: -10.356157589 + -13.5 = -23.856157589 v = -23.856157589 Simplifying v = -23.856157589Solution
