Simplifying (4x2) + 80x + 397 = 0 Reorder the terms: 397 + 80x + (4x2) = 0 Solving 397 + 80x + (4x2) = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. 99.25 + 20x + x2 = 0 Move the constant term to the right: Add '-99.25' to each side of the equation. 99.25 + 20x + -99.25 + x2 = 0 + -99.25 Reorder the terms: 99.25 + -99.25 + 20x + x2 = 0 + -99.25 Combine like terms: 99.25 + -99.25 = 0.00 0.00 + 20x + x2 = 0 + -99.25 20x + x2 = 0 + -99.25 Combine like terms: 0 + -99.25 = -99.25 20x + x2 = -99.25 The x term is 20x. Take half its coefficient (10). Square it (100) and add it to both sides. Add '100' to each side of the equation. 20x + 100 + x2 = -99.25 + 100 Reorder the terms: 100 + 20x + x2 = -99.25 + 100 Combine like terms: -99.25 + 100 = 0.75 100 + 20x + x2 = 0.75 Factor a perfect square on the left side: ((x) + 10)((x) + 10) = 0.75 Calculate the square root of the right side: 0.866025404 Break this problem into two subproblems by setting ((x) + 10) equal to 0.866025404 and -0.866025404.Subproblem 1
(x) + 10 = 0.866025404 Simplifying (x) + 10 = 0.866025404 x + 10 = 0.866025404 Reorder the terms: 10 + x = 0.866025404 Solving 10 + x = 0.866025404 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-10' to each side of the equation. 10 + -10 + x = 0.866025404 + -10 Combine like terms: 10 + -10 = 0 0 + x = 0.866025404 + -10 x = 0.866025404 + -10 Combine like terms: 0.866025404 + -10 = -9.133974596 x = -9.133974596 Simplifying x = -9.133974596Subproblem 2
(x) + 10 = -0.866025404 Simplifying (x) + 10 = -0.866025404 x + 10 = -0.866025404 Reorder the terms: 10 + x = -0.866025404 Solving 10 + x = -0.866025404 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-10' to each side of the equation. 10 + -10 + x = -0.866025404 + -10 Combine like terms: 10 + -10 = 0 0 + x = -0.866025404 + -10 x = -0.866025404 + -10 Combine like terms: -0.866025404 + -10 = -10.866025404 x = -10.866025404 Simplifying x = -10.866025404Solution
The solution to the problem is based on the solutions from the subproblems. x = {-9.133974596, -10.866025404}
