Simplifying (7v2 + -5v + -6) + (v2 + -3v + 2) = 0 Reorder the terms: (-6 + -5v + 7v2) + (v2 + -3v + 2) = 0 Remove parenthesis around (-6 + -5v + 7v2) -6 + -5v + 7v2 + (v2 + -3v + 2) = 0 Reorder the terms: -6 + -5v + 7v2 + (2 + -3v + v2) = 0 Remove parenthesis around (2 + -3v + v2) -6 + -5v + 7v2 + 2 + -3v + v2 = 0 Reorder the terms: -6 + 2 + -5v + -3v + 7v2 + v2 = 0 Combine like terms: -6 + 2 = -4 -4 + -5v + -3v + 7v2 + v2 = 0 Combine like terms: -5v + -3v = -8v -4 + -8v + 7v2 + v2 = 0 Combine like terms: 7v2 + v2 = 8v2 -4 + -8v + 8v2 = 0 Solving -4 + -8v + 8v2 = 0 Solving for variable 'v'. Factor out the Greatest Common Factor (GCF), '4'. 4(-1 + -2v + 2v2) = 0 Ignore the factor 4.Subproblem 1
Set the factor '(-1 + -2v + 2v2)' equal to zero and attempt to solve: Simplifying -1 + -2v + 2v2 = 0 Solving -1 + -2v + 2v2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -0.5 + -1v + v2 = 0 Move the constant term to the right: Add '0.5' to each side of the equation. -0.5 + -1v + 0.5 + v2 = 0 + 0.5 Reorder the terms: -0.5 + 0.5 + -1v + v2 = 0 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + -1v + v2 = 0 + 0.5 -1v + v2 = 0 + 0.5 Combine like terms: 0 + 0.5 = 0.5 -1v + v2 = 0.5 The v term is -1v. Take half its coefficient (-0.5). Square it (0.25) and add it to both sides. Add '0.25' to each side of the equation. -1v + 0.25 + v2 = 0.5 + 0.25 Reorder the terms: 0.25 + -1v + v2 = 0.5 + 0.25 Combine like terms: 0.5 + 0.25 = 0.75 0.25 + -1v + v2 = 0.75 Factor a perfect square on the left side: (v + -0.5)(v + -0.5) = 0.75 Calculate the square root of the right side: 0.866025404 Break this problem into two subproblems by setting (v + -0.5) equal to 0.866025404 and -0.866025404.Subproblem 1
v + -0.5 = 0.866025404 Simplifying v + -0.5 = 0.866025404 Reorder the terms: -0.5 + v = 0.866025404 Solving -0.5 + v = 0.866025404 Solving for variable 'v'. Move all terms containing v to the left, all other terms to the right. Add '0.5' to each side of the equation. -0.5 + 0.5 + v = 0.866025404 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + v = 0.866025404 + 0.5 v = 0.866025404 + 0.5 Combine like terms: 0.866025404 + 0.5 = 1.366025404 v = 1.366025404 Simplifying v = 1.366025404Subproblem 2
v + -0.5 = -0.866025404 Simplifying v + -0.5 = -0.866025404 Reorder the terms: -0.5 + v = -0.866025404 Solving -0.5 + v = -0.866025404 Solving for variable 'v'. Move all terms containing v to the left, all other terms to the right. Add '0.5' to each side of the equation. -0.5 + 0.5 + v = -0.866025404 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + v = -0.866025404 + 0.5 v = -0.866025404 + 0.5 Combine like terms: -0.866025404 + 0.5 = -0.366025404 v = -0.366025404 Simplifying v = -0.366025404Solution
