Simplifying -0.1x2 + 6.6x + 8.2 = 0 Reorder the terms: 8.2 + 6.6x + -0.1x2 = 0 Solving 8.2 + 6.6x + -0.1x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by -0.1 the coefficient of the squared term: Divide each side by '-0.1'. -82 + -66x + x2 = 0 Move the constant term to the right: Add '82' to each side of the equation. -82 + -66x + 82 + x2 = 0 + 82 Reorder the terms: -82 + 82 + -66x + x2 = 0 + 82 Combine like terms: -82 + 82 = 0 0 + -66x + x2 = 0 + 82 -66x + x2 = 0 + 82 Combine like terms: 0 + 82 = 82 -66x + x2 = 82 The x term is -66x. Take half its coefficient (-33). Square it (1089) and add it to both sides. Add '1089' to each side of the equation. -66x + 1089 + x2 = 82 + 1089 Reorder the terms: 1089 + -66x + x2 = 82 + 1089 Combine like terms: 82 + 1089 = 1171 1089 + -66x + x2 = 1171 Factor a perfect square on the left side: (x + -33)(x + -33) = 1171 Calculate the square root of the right side: 34.219877265 Break this problem into two subproblems by setting (x + -33) equal to 34.219877265 and -34.219877265.Subproblem 1
x + -33 = 34.219877265 Simplifying x + -33 = 34.219877265 Reorder the terms: -33 + x = 34.219877265 Solving -33 + x = 34.219877265 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '33' to each side of the equation. -33 + 33 + x = 34.219877265 + 33 Combine like terms: -33 + 33 = 0 0 + x = 34.219877265 + 33 x = 34.219877265 + 33 Combine like terms: 34.219877265 + 33 = 67.219877265 x = 67.219877265 Simplifying x = 67.219877265Subproblem 2
x + -33 = -34.219877265 Simplifying x + -33 = -34.219877265 Reorder the terms: -33 + x = -34.219877265 Solving -33 + x = -34.219877265 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '33' to each side of the equation. -33 + 33 + x = -34.219877265 + 33 Combine like terms: -33 + 33 = 0 0 + x = -34.219877265 + 33 x = -34.219877265 + 33 Combine like terms: -34.219877265 + 33 = -1.219877265 x = -1.219877265 Simplifying x = -1.219877265Solution
