Simplifying (4v2 + -2v + -6) + (5v2 + -7v + 3) = 0 Reorder the terms: (-6 + -2v + 4v2) + (5v2 + -7v + 3) = 0 Remove parenthesis around (-6 + -2v + 4v2) -6 + -2v + 4v2 + (5v2 + -7v + 3) = 0 Reorder the terms: -6 + -2v + 4v2 + (3 + -7v + 5v2) = 0 Remove parenthesis around (3 + -7v + 5v2) -6 + -2v + 4v2 + 3 + -7v + 5v2 = 0 Reorder the terms: -6 + 3 + -2v + -7v + 4v2 + 5v2 = 0 Combine like terms: -6 + 3 = -3 -3 + -2v + -7v + 4v2 + 5v2 = 0 Combine like terms: -2v + -7v = -9v -3 + -9v + 4v2 + 5v2 = 0 Combine like terms: 4v2 + 5v2 = 9v2 -3 + -9v + 9v2 = 0 Solving -3 + -9v + 9v2 = 0 Solving for variable 'v'. Factor out the Greatest Common Factor (GCF), '3'. 3(-1 + -3v + 3v2) = 0 Ignore the factor 3.Subproblem 1
Set the factor '(-1 + -3v + 3v2)' equal to zero and attempt to solve: Simplifying -1 + -3v + 3v2 = 0 Solving -1 + -3v + 3v2 = 0 Begin completing the square. Divide all terms by 3 the coefficient of the squared term: Divide each side by '3'. -0.3333333333 + -1v + v2 = 0 Move the constant term to the right: Add '0.3333333333' to each side of the equation. -0.3333333333 + -1v + 0.3333333333 + v2 = 0 + 0.3333333333 Reorder the terms: -0.3333333333 + 0.3333333333 + -1v + v2 = 0 + 0.3333333333 Combine like terms: -0.3333333333 + 0.3333333333 = 0.0000000000 0.0000000000 + -1v + v2 = 0 + 0.3333333333 -1v + v2 = 0 + 0.3333333333 Combine like terms: 0 + 0.3333333333 = 0.3333333333 -1v + v2 = 0.3333333333 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 = 0.3333333333 + 0.25 Reorder the terms: 0.25 + -1v + v2 = 0.3333333333 + 0.25 Combine like terms: 0.3333333333 + 0.25 = 0.5833333333 0.25 + -1v + v2 = 0.5833333333 Factor a perfect square on the left side: (v + -0.5)(v + -0.5) = 0.5833333333 Calculate the square root of the right side: 0.763762616 Break this problem into two subproblems by setting (v + -0.5) equal to 0.763762616 and -0.763762616.Subproblem 1
v + -0.5 = 0.763762616 Simplifying v + -0.5 = 0.763762616 Reorder the terms: -0.5 + v = 0.763762616 Solving -0.5 + v = 0.763762616 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 = 0.763762616 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + v = 0.763762616 + 0.5 v = 0.763762616 + 0.5 Combine like terms: 0.763762616 + 0.5 = 1.263762616 v = 1.263762616 Simplifying v = 1.263762616Subproblem 2
v + -0.5 = -0.763762616 Simplifying v + -0.5 = -0.763762616 Reorder the terms: -0.5 + v = -0.763762616 Solving -0.5 + v = -0.763762616 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 = -0.763762616 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + v = -0.763762616 + 0.5 v = -0.763762616 + 0.5 Combine like terms: -0.763762616 + 0.5 = -0.263762616 v = -0.263762616 Simplifying v = -0.263762616Solution
