Simplifying -4 = -1 + -3v(2v + 3) Reorder the terms: -4 = -1 + -3v(3 + 2v) -4 = -1 + (3 * -3v + 2v * -3v) -4 = -1 + (-9v + -6v2) Solving -4 = -1 + -9v + -6v2 Solving for variable 'v'. Combine like terms: -4 + 1 = -3 -3 + 9v + 6v2 = -1 + -9v + -6v2 + 1 + 9v + 6v2 Reorder the terms: -3 + 9v + 6v2 = -1 + 1 + -9v + 9v + -6v2 + 6v2 Combine like terms: -1 + 1 = 0 -3 + 9v + 6v2 = 0 + -9v + 9v + -6v2 + 6v2 -3 + 9v + 6v2 = -9v + 9v + -6v2 + 6v2 Combine like terms: -9v + 9v = 0 -3 + 9v + 6v2 = 0 + -6v2 + 6v2 -3 + 9v + 6v2 = -6v2 + 6v2 Combine like terms: -6v2 + 6v2 = 0 -3 + 9v + 6v2 = 0 Factor out the Greatest Common Factor (GCF), '3'. 3(-1 + 3v + 2v2) = 0 Ignore the factor 3.Subproblem 1
Set the factor '(-1 + 3v + 2v2)' equal to zero and attempt to solve: Simplifying -1 + 3v + 2v2 = 0 Solving -1 + 3v + 2v2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -0.5 + 1.5v + v2 = 0 Move the constant term to the right: Add '0.5' to each side of the equation. -0.5 + 1.5v + 0.5 + v2 = 0 + 0.5 Reorder the terms: -0.5 + 0.5 + 1.5v + v2 = 0 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + 1.5v + v2 = 0 + 0.5 1.5v + v2 = 0 + 0.5 Combine like terms: 0 + 0.5 = 0.5 1.5v + v2 = 0.5 The v term is 1.5v. Take half its coefficient (0.75). Square it (0.5625) and add it to both sides. Add '0.5625' to each side of the equation. 1.5v + 0.5625 + v2 = 0.5 + 0.5625 Reorder the terms: 0.5625 + 1.5v + v2 = 0.5 + 0.5625 Combine like terms: 0.5 + 0.5625 = 1.0625 0.5625 + 1.5v + v2 = 1.0625 Factor a perfect square on the left side: (v + 0.75)(v + 0.75) = 1.0625 Calculate the square root of the right side: 1.030776406 Break this problem into two subproblems by setting (v + 0.75) equal to 1.030776406 and -1.030776406.Subproblem 1
v + 0.75 = 1.030776406 Simplifying v + 0.75 = 1.030776406 Reorder the terms: 0.75 + v = 1.030776406 Solving 0.75 + v = 1.030776406 Solving for variable 'v'. Move all terms containing v to the left, all other terms to the right. Add '-0.75' to each side of the equation. 0.75 + -0.75 + v = 1.030776406 + -0.75 Combine like terms: 0.75 + -0.75 = 0.00 0.00 + v = 1.030776406 + -0.75 v = 1.030776406 + -0.75 Combine like terms: 1.030776406 + -0.75 = 0.280776406 v = 0.280776406 Simplifying v = 0.280776406Subproblem 2
v + 0.75 = -1.030776406 Simplifying v + 0.75 = -1.030776406 Reorder the terms: 0.75 + v = -1.030776406 Solving 0.75 + v = -1.030776406 Solving for variable 'v'. Move all terms containing v to the left, all other terms to the right. Add '-0.75' to each side of the equation. 0.75 + -0.75 + v = -1.030776406 + -0.75 Combine like terms: 0.75 + -0.75 = 0.00 0.00 + v = -1.030776406 + -0.75 v = -1.030776406 + -0.75 Combine like terms: -1.030776406 + -0.75 = -1.780776406 v = -1.780776406 Simplifying v = -1.780776406Solution
