Simplifying (4v2 + -4v + 7) + -1(9v2 + 7v + -5) + (3v2 + 7v + 9) = 0 Reorder the terms: (7 + -4v + 4v2) + -1(9v2 + 7v + -5) + (3v2 + 7v + 9) = 0 Remove parenthesis around (7 + -4v + 4v2) 7 + -4v + 4v2 + -1(9v2 + 7v + -5) + (3v2 + 7v + 9) = 0 Reorder the terms: 7 + -4v + 4v2 + -1(-5 + 7v + 9v2) + (3v2 + 7v + 9) = 0 7 + -4v + 4v2 + (-5 * -1 + 7v * -1 + 9v2 * -1) + (3v2 + 7v + 9) = 0 7 + -4v + 4v2 + (5 + -7v + -9v2) + (3v2 + 7v + 9) = 0 Reorder the terms: 7 + -4v + 4v2 + 5 + -7v + -9v2 + (9 + 7v + 3v2) = 0 Remove parenthesis around (9 + 7v + 3v2) 7 + -4v + 4v2 + 5 + -7v + -9v2 + 9 + 7v + 3v2 = 0 Reorder the terms: 7 + 5 + 9 + -4v + -7v + 7v + 4v2 + -9v2 + 3v2 = 0 Combine like terms: 7 + 5 = 12 12 + 9 + -4v + -7v + 7v + 4v2 + -9v2 + 3v2 = 0 Combine like terms: 12 + 9 = 21 21 + -4v + -7v + 7v + 4v2 + -9v2 + 3v2 = 0 Combine like terms: -4v + -7v = -11v 21 + -11v + 7v + 4v2 + -9v2 + 3v2 = 0 Combine like terms: -11v + 7v = -4v 21 + -4v + 4v2 + -9v2 + 3v2 = 0 Combine like terms: 4v2 + -9v2 = -5v2 21 + -4v + -5v2 + 3v2 = 0 Combine like terms: -5v2 + 3v2 = -2v2 21 + -4v + -2v2 = 0 Solving 21 + -4v + -2v2 = 0 Solving for variable 'v'. Begin completing the square. Divide all terms by -2 the coefficient of the squared term: Divide each side by '-2'. -10.5 + 2v + v2 = 0 Move the constant term to the right: Add '10.5' to each side of the equation. -10.5 + 2v + 10.5 + v2 = 0 + 10.5 Reorder the terms: -10.5 + 10.5 + 2v + v2 = 0 + 10.5 Combine like terms: -10.5 + 10.5 = 0.0 0.0 + 2v + v2 = 0 + 10.5 2v + v2 = 0 + 10.5 Combine like terms: 0 + 10.5 = 10.5 2v + v2 = 10.5 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 = 10.5 + 1 Reorder the terms: 1 + 2v + v2 = 10.5 + 1 Combine like terms: 10.5 + 1 = 11.5 1 + 2v + v2 = 11.5 Factor a perfect square on the left side: (v + 1)(v + 1) = 11.5 Calculate the square root of the right side: 3.391164992 Break this problem into two subproblems by setting (v + 1) equal to 3.391164992 and -3.391164992.Subproblem 1
v + 1 = 3.391164992 Simplifying v + 1 = 3.391164992 Reorder the terms: 1 + v = 3.391164992 Solving 1 + v = 3.391164992 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 = 3.391164992 + -1 Combine like terms: 1 + -1 = 0 0 + v = 3.391164992 + -1 v = 3.391164992 + -1 Combine like terms: 3.391164992 + -1 = 2.391164992 v = 2.391164992 Simplifying v = 2.391164992Subproblem 2
v + 1 = -3.391164992 Simplifying v + 1 = -3.391164992 Reorder the terms: 1 + v = -3.391164992 Solving 1 + v = -3.391164992 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 = -3.391164992 + -1 Combine like terms: 1 + -1 = 0 0 + v = -3.391164992 + -1 v = -3.391164992 + -1 Combine like terms: -3.391164992 + -1 = -4.391164992 v = -4.391164992 Simplifying v = -4.391164992Solution
The solution to the problem is based on the solutions from the subproblems. v = {2.391164992, -4.391164992}
