Simplifying (6v2 + -4v + -2) + (3v2 + -5v + 1) = 0 Reorder the terms: (-2 + -4v + 6v2) + (3v2 + -5v + 1) = 0 Remove parenthesis around (-2 + -4v + 6v2) -2 + -4v + 6v2 + (3v2 + -5v + 1) = 0 Reorder the terms: -2 + -4v + 6v2 + (1 + -5v + 3v2) = 0 Remove parenthesis around (1 + -5v + 3v2) -2 + -4v + 6v2 + 1 + -5v + 3v2 = 0 Reorder the terms: -2 + 1 + -4v + -5v + 6v2 + 3v2 = 0 Combine like terms: -2 + 1 = -1 -1 + -4v + -5v + 6v2 + 3v2 = 0 Combine like terms: -4v + -5v = -9v -1 + -9v + 6v2 + 3v2 = 0 Combine like terms: 6v2 + 3v2 = 9v2 -1 + -9v + 9v2 = 0 Solving -1 + -9v + 9v2 = 0 Solving for variable 'v'. Begin completing the square. Divide all terms by 9 the coefficient of the squared term: Divide each side by '9'. -0.1111111111 + -1v + v2 = 0 Move the constant term to the right: Add '0.1111111111' to each side of the equation. -0.1111111111 + -1v + 0.1111111111 + v2 = 0 + 0.1111111111 Reorder the terms: -0.1111111111 + 0.1111111111 + -1v + v2 = 0 + 0.1111111111 Combine like terms: -0.1111111111 + 0.1111111111 = 0.0000000000 0.0000000000 + -1v + v2 = 0 + 0.1111111111 -1v + v2 = 0 + 0.1111111111 Combine like terms: 0 + 0.1111111111 = 0.1111111111 -1v + v2 = 0.1111111111 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 = 0.1111111111 + 0.25 Reorder the terms: 0.25 + -1v + v2 = 0.1111111111 + 0.25 Combine like terms: 0.1111111111 + 0.25 = 0.3611111111 0.25 + -1v + v2 = 0.3611111111 Factor a perfect square on the left side: (v + -0.5)(v + -0.5) = 0.3611111111 Calculate the square root of the right side: 0.600925213 Break this problem into two subproblems by setting (v + -0.5) equal to 0.600925213 and -0.600925213.Subproblem 1
v + -0.5 = 0.600925213 Simplifying v + -0.5 = 0.600925213 Reorder the terms: -0.5 + v = 0.600925213 Solving -0.5 + v = 0.600925213 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 = 0.600925213 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + v = 0.600925213 + 0.5 v = 0.600925213 + 0.5 Combine like terms: 0.600925213 + 0.5 = 1.100925213 v = 1.100925213 Simplifying v = 1.100925213Subproblem 2
v + -0.5 = -0.600925213 Simplifying v + -0.5 = -0.600925213 Reorder the terms: -0.5 + v = -0.600925213 Solving -0.5 + v = -0.600925213 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 = -0.600925213 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + v = -0.600925213 + 0.5 v = -0.600925213 + 0.5 Combine like terms: -0.600925213 + 0.5 = -0.100925213 v = -0.100925213 Simplifying v = -0.100925213Solution
The solution to the problem is based on the solutions from the subproblems. v = {1.100925213, -0.100925213}
