Simplifying 3v2 + 6v + 2 = 0 Reorder the terms: 2 + 6v + 3v2 = 0 Solving 2 + 6v + 3v2 = 0 Solving for variable 'v'. Begin completing the square. Divide all terms by 3 the coefficient of the squared term: Divide each side by '3'. 0.6666666667 + 2v + v2 = 0 Move the constant term to the right: Add '-0.6666666667' to each side of the equation. 0.6666666667 + 2v + -0.6666666667 + v2 = 0 + -0.6666666667 Reorder the terms: 0.6666666667 + -0.6666666667 + 2v + v2 = 0 + -0.6666666667 Combine like terms: 0.6666666667 + -0.6666666667 = 0.0000000000 0.0000000000 + 2v + v2 = 0 + -0.6666666667 2v + v2 = 0 + -0.6666666667 Combine like terms: 0 + -0.6666666667 = -0.6666666667 2v + v2 = -0.6666666667 The v term is 2v. Take half its coefficient (1). Square it (1) and add it to both sides. Add '1' to each side of the equation. 2v + 1 + v2 = -0.6666666667 + 1 Reorder the terms: 1 + 2v + v2 = -0.6666666667 + 1 Combine like terms: -0.6666666667 + 1 = 0.3333333333 1 + 2v + v2 = 0.3333333333 Factor a perfect square on the left side: (v + 1)(v + 1) = 0.3333333333 Calculate the square root of the right side: 0.577350269 Break this problem into two subproblems by setting (v + 1) equal to 0.577350269 and -0.577350269.Subproblem 1
v + 1 = 0.577350269 Simplifying v + 1 = 0.577350269 Reorder the terms: 1 + v = 0.577350269 Solving 1 + v = 0.577350269 Solving for variable 'v'. Move all terms containing v to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + v = 0.577350269 + -1 Combine like terms: 1 + -1 = 0 0 + v = 0.577350269 + -1 v = 0.577350269 + -1 Combine like terms: 0.577350269 + -1 = -0.422649731 v = -0.422649731 Simplifying v = -0.422649731Subproblem 2
v + 1 = -0.577350269 Simplifying v + 1 = -0.577350269 Reorder the terms: 1 + v = -0.577350269 Solving 1 + v = -0.577350269 Solving for variable 'v'. Move all terms containing v to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + v = -0.577350269 + -1 Combine like terms: 1 + -1 = 0 0 + v = -0.577350269 + -1 v = -0.577350269 + -1 Combine like terms: -0.577350269 + -1 = -1.577350269 v = -1.577350269 Simplifying v = -1.577350269Solution
