Simplifying 4x2 + 1.6x + -3.2169 = 0 Reorder the terms: -3.2169 + 1.6x + 4x2 = 0 Solving -3.2169 + 1.6x + 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'. -0.804225 + 0.4x + x2 = 0 Move the constant term to the right: Add '0.804225' to each side of the equation. -0.804225 + 0.4x + 0.804225 + x2 = 0 + 0.804225 Reorder the terms: -0.804225 + 0.804225 + 0.4x + x2 = 0 + 0.804225 Combine like terms: -0.804225 + 0.804225 = 0.000000 0.000000 + 0.4x + x2 = 0 + 0.804225 0.4x + x2 = 0 + 0.804225 Combine like terms: 0 + 0.804225 = 0.804225 0.4x + x2 = 0.804225 The x term is 0.4x. Take half its coefficient (0.2). Square it (0.04) and add it to both sides. Add '0.04' to each side of the equation. 0.4x + 0.04 + x2 = 0.804225 + 0.04 Reorder the terms: 0.04 + 0.4x + x2 = 0.804225 + 0.04 Combine like terms: 0.804225 + 0.04 = 0.844225 0.04 + 0.4x + x2 = 0.844225 Factor a perfect square on the left side: (x + 0.2)(x + 0.2) = 0.844225 Calculate the square root of the right side: 0.918817174 Break this problem into two subproblems by setting (x + 0.2) equal to 0.918817174 and -0.918817174.Subproblem 1
x + 0.2 = 0.918817174 Simplifying x + 0.2 = 0.918817174 Reorder the terms: 0.2 + x = 0.918817174 Solving 0.2 + x = 0.918817174 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.2' to each side of the equation. 0.2 + -0.2 + x = 0.918817174 + -0.2 Combine like terms: 0.2 + -0.2 = 0.0 0.0 + x = 0.918817174 + -0.2 x = 0.918817174 + -0.2 Combine like terms: 0.918817174 + -0.2 = 0.718817174 x = 0.718817174 Simplifying x = 0.718817174Subproblem 2
x + 0.2 = -0.918817174 Simplifying x + 0.2 = -0.918817174 Reorder the terms: 0.2 + x = -0.918817174 Solving 0.2 + x = -0.918817174 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.2' to each side of the equation. 0.2 + -0.2 + x = -0.918817174 + -0.2 Combine like terms: 0.2 + -0.2 = 0.0 0.0 + x = -0.918817174 + -0.2 x = -0.918817174 + -0.2 Combine like terms: -0.918817174 + -0.2 = -1.118817174 x = -1.118817174 Simplifying x = -1.118817174Solution
The solution to the problem is based on the solutions from the subproblems. x = {0.718817174, -1.118817174}
