Simplifying -8v2 + 18v + 7 = 0 Reorder the terms: 7 + 18v + -8v2 = 0 Solving 7 + 18v + -8v2 = 0 Solving for variable 'v'. Begin completing the square. Divide all terms by -8 the coefficient of the squared term: Divide each side by '-8'. -0.875 + -2.25v + v2 = 0 Move the constant term to the right: Add '0.875' to each side of the equation. -0.875 + -2.25v + 0.875 + v2 = 0 + 0.875 Reorder the terms: -0.875 + 0.875 + -2.25v + v2 = 0 + 0.875 Combine like terms: -0.875 + 0.875 = 0.000 0.000 + -2.25v + v2 = 0 + 0.875 -2.25v + v2 = 0 + 0.875 Combine like terms: 0 + 0.875 = 0.875 -2.25v + v2 = 0.875 The v term is -2.25v. Take half its coefficient (-1.125). Square it (1.265625) and add it to both sides. Add '1.265625' to each side of the equation. -2.25v + 1.265625 + v2 = 0.875 + 1.265625 Reorder the terms: 1.265625 + -2.25v + v2 = 0.875 + 1.265625 Combine like terms: 0.875 + 1.265625 = 2.140625 1.265625 + -2.25v + v2 = 2.140625 Factor a perfect square on the left side: (v + -1.125)(v + -1.125) = 2.140625 Calculate the square root of the right side: 1.463087489 Break this problem into two subproblems by setting (v + -1.125) equal to 1.463087489 and -1.463087489.Subproblem 1
v + -1.125 = 1.463087489 Simplifying v + -1.125 = 1.463087489 Reorder the terms: -1.125 + v = 1.463087489 Solving -1.125 + v = 1.463087489 Solving for variable 'v'. Move all terms containing v to the left, all other terms to the right. Add '1.125' to each side of the equation. -1.125 + 1.125 + v = 1.463087489 + 1.125 Combine like terms: -1.125 + 1.125 = 0.000 0.000 + v = 1.463087489 + 1.125 v = 1.463087489 + 1.125 Combine like terms: 1.463087489 + 1.125 = 2.588087489 v = 2.588087489 Simplifying v = 2.588087489Subproblem 2
v + -1.125 = -1.463087489 Simplifying v + -1.125 = -1.463087489 Reorder the terms: -1.125 + v = -1.463087489 Solving -1.125 + v = -1.463087489 Solving for variable 'v'. Move all terms containing v to the left, all other terms to the right. Add '1.125' to each side of the equation. -1.125 + 1.125 + v = -1.463087489 + 1.125 Combine like terms: -1.125 + 1.125 = 0.000 0.000 + v = -1.463087489 + 1.125 v = -1.463087489 + 1.125 Combine like terms: -1.463087489 + 1.125 = -0.338087489 v = -0.338087489 Simplifying v = -0.338087489Solution
The solution to the problem is based on the solutions from the subproblems. v = {2.588087489, -0.338087489}
