Simplifying 49v2 + -49v + 9 = 0 Reorder the terms: 9 + -49v + 49v2 = 0 Solving 9 + -49v + 49v2 = 0 Solving for variable 'v'. Begin completing the square. Divide all terms by 49 the coefficient of the squared term: Divide each side by '49'. 0.1836734694 + -1v + v2 = 0 Move the constant term to the right: Add '-0.1836734694' to each side of the equation. 0.1836734694 + -1v + -0.1836734694 + v2 = 0 + -0.1836734694 Reorder the terms: 0.1836734694 + -0.1836734694 + -1v + v2 = 0 + -0.1836734694 Combine like terms: 0.1836734694 + -0.1836734694 = 0.0000000000 0.0000000000 + -1v + v2 = 0 + -0.1836734694 -1v + v2 = 0 + -0.1836734694 Combine like terms: 0 + -0.1836734694 = -0.1836734694 -1v + v2 = -0.1836734694 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 = -0.1836734694 + 0.25 Reorder the terms: 0.25 + -1v + v2 = -0.1836734694 + 0.25 Combine like terms: -0.1836734694 + 0.25 = 0.0663265306 0.25 + -1v + v2 = 0.0663265306 Factor a perfect square on the left side: (v + -0.5)(v + -0.5) = 0.0663265306 Calculate the square root of the right side: 0.257539377 Break this problem into two subproblems by setting (v + -0.5) equal to 0.257539377 and -0.257539377.Subproblem 1
v + -0.5 = 0.257539377 Simplifying v + -0.5 = 0.257539377 Reorder the terms: -0.5 + v = 0.257539377 Solving -0.5 + v = 0.257539377 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 = 0.257539377 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + v = 0.257539377 + 0.5 v = 0.257539377 + 0.5 Combine like terms: 0.257539377 + 0.5 = 0.757539377 v = 0.757539377 Simplifying v = 0.757539377Subproblem 2
v + -0.5 = -0.257539377 Simplifying v + -0.5 = -0.257539377 Reorder the terms: -0.5 + v = -0.257539377 Solving -0.5 + v = -0.257539377 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 = -0.257539377 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + v = -0.257539377 + 0.5 v = -0.257539377 + 0.5 Combine like terms: -0.257539377 + 0.5 = 0.242460623 v = 0.242460623 Simplifying v = 0.242460623Solution
The solution to the problem is based on the solutions from the subproblems. v = {0.757539377, 0.242460623}
