Simplifying x2 + 34x + 81 = 0 Reorder the terms: 81 + 34x + x2 = 0 Solving 81 + 34x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-81' to each side of the equation. 81 + 34x + -81 + x2 = 0 + -81 Reorder the terms: 81 + -81 + 34x + x2 = 0 + -81 Combine like terms: 81 + -81 = 0 0 + 34x + x2 = 0 + -81 34x + x2 = 0 + -81 Combine like terms: 0 + -81 = -81 34x + x2 = -81 The x term is 34x. Take half its coefficient (17). Square it (289) and add it to both sides. Add '289' to each side of the equation. 34x + 289 + x2 = -81 + 289 Reorder the terms: 289 + 34x + x2 = -81 + 289 Combine like terms: -81 + 289 = 208 289 + 34x + x2 = 208 Factor a perfect square on the left side: (x + 17)(x + 17) = 208 Calculate the square root of the right side: 14.422205102 Break this problem into two subproblems by setting (x + 17) equal to 14.422205102 and -14.422205102.Subproblem 1
x + 17 = 14.422205102 Simplifying x + 17 = 14.422205102 Reorder the terms: 17 + x = 14.422205102 Solving 17 + x = 14.422205102 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-17' to each side of the equation. 17 + -17 + x = 14.422205102 + -17 Combine like terms: 17 + -17 = 0 0 + x = 14.422205102 + -17 x = 14.422205102 + -17 Combine like terms: 14.422205102 + -17 = -2.577794898 x = -2.577794898 Simplifying x = -2.577794898Subproblem 2
x + 17 = -14.422205102 Simplifying x + 17 = -14.422205102 Reorder the terms: 17 + x = -14.422205102 Solving 17 + x = -14.422205102 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-17' to each side of the equation. 17 + -17 + x = -14.422205102 + -17 Combine like terms: 17 + -17 = 0 0 + x = -14.422205102 + -17 x = -14.422205102 + -17 Combine like terms: -14.422205102 + -17 = -31.422205102 x = -31.422205102 Simplifying x = -31.422205102Solution
The solution to the problem is based on the solutions from the subproblems. x = {-2.577794898, -31.422205102}
