Simplifying 10v2 + 8v + -1 = 0 Reorder the terms: -1 + 8v + 10v2 = 0 Solving -1 + 8v + 10v2 = 0 Solving for variable 'v'. Begin completing the square. Divide all terms by 10 the coefficient of the squared term: Divide each side by '10'. -0.1 + 0.8v + v2 = 0 Move the constant term to the right: Add '0.1' to each side of the equation. -0.1 + 0.8v + 0.1 + v2 = 0 + 0.1 Reorder the terms: -0.1 + 0.1 + 0.8v + v2 = 0 + 0.1 Combine like terms: -0.1 + 0.1 = 0.0 0.0 + 0.8v + v2 = 0 + 0.1 0.8v + v2 = 0 + 0.1 Combine like terms: 0 + 0.1 = 0.1 0.8v + v2 = 0.1 The v term is 0.8v. Take half its coefficient (0.4). Square it (0.16) and add it to both sides. Add '0.16' to each side of the equation. 0.8v + 0.16 + v2 = 0.1 + 0.16 Reorder the terms: 0.16 + 0.8v + v2 = 0.1 + 0.16 Combine like terms: 0.1 + 0.16 = 0.26 0.16 + 0.8v + v2 = 0.26 Factor a perfect square on the left side: (v + 0.4)(v + 0.4) = 0.26 Calculate the square root of the right side: 0.509901951 Break this problem into two subproblems by setting (v + 0.4) equal to 0.509901951 and -0.509901951.Subproblem 1
v + 0.4 = 0.509901951 Simplifying v + 0.4 = 0.509901951 Reorder the terms: 0.4 + v = 0.509901951 Solving 0.4 + v = 0.509901951 Solving for variable 'v'. Move all terms containing v to the left, all other terms to the right. Add '-0.4' to each side of the equation. 0.4 + -0.4 + v = 0.509901951 + -0.4 Combine like terms: 0.4 + -0.4 = 0.0 0.0 + v = 0.509901951 + -0.4 v = 0.509901951 + -0.4 Combine like terms: 0.509901951 + -0.4 = 0.109901951 v = 0.109901951 Simplifying v = 0.109901951Subproblem 2
v + 0.4 = -0.509901951 Simplifying v + 0.4 = -0.509901951 Reorder the terms: 0.4 + v = -0.509901951 Solving 0.4 + v = -0.509901951 Solving for variable 'v'. Move all terms containing v to the left, all other terms to the right. Add '-0.4' to each side of the equation. 0.4 + -0.4 + v = -0.509901951 + -0.4 Combine like terms: 0.4 + -0.4 = 0.0 0.0 + v = -0.509901951 + -0.4 v = -0.509901951 + -0.4 Combine like terms: -0.509901951 + -0.4 = -0.909901951 v = -0.909901951 Simplifying v = -0.909901951Solution
The solution to the problem is based on the solutions from the subproblems. v = {0.109901951, -0.909901951}
