Simplifying 2x(4x + 8) = 3x + -4 Reorder the terms: 2x(8 + 4x) = 3x + -4 (8 * 2x + 4x * 2x) = 3x + -4 (16x + 8x2) = 3x + -4 Reorder the terms: 16x + 8x2 = -4 + 3x Solving 16x + 8x2 = -4 + 3x Solving for variable 'x'. Reorder the terms: 4 + 16x + -3x + 8x2 = -4 + 3x + 4 + -3x Combine like terms: 16x + -3x = 13x 4 + 13x + 8x2 = -4 + 3x + 4 + -3x Reorder the terms: 4 + 13x + 8x2 = -4 + 4 + 3x + -3x Combine like terms: -4 + 4 = 0 4 + 13x + 8x2 = 0 + 3x + -3x 4 + 13x + 8x2 = 3x + -3x Combine like terms: 3x + -3x = 0 4 + 13x + 8x2 = 0 Begin completing the square. Divide all terms by 8 the coefficient of the squared term: Divide each side by '8'. 0.5 + 1.625x + x2 = 0 Move the constant term to the right: Add '-0.5' to each side of the equation. 0.5 + 1.625x + -0.5 + x2 = 0 + -0.5 Reorder the terms: 0.5 + -0.5 + 1.625x + x2 = 0 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + 1.625x + x2 = 0 + -0.5 1.625x + x2 = 0 + -0.5 Combine like terms: 0 + -0.5 = -0.5 1.625x + x2 = -0.5 The x term is 1.625x. Take half its coefficient (0.8125). Square it (0.66015625) and add it to both sides. Add '0.66015625' to each side of the equation. 1.625x + 0.66015625 + x2 = -0.5 + 0.66015625 Reorder the terms: 0.66015625 + 1.625x + x2 = -0.5 + 0.66015625 Combine like terms: -0.5 + 0.66015625 = 0.16015625 0.66015625 + 1.625x + x2 = 0.16015625 Factor a perfect square on the left side: (x + 0.8125)(x + 0.8125) = 0.16015625 Calculate the square root of the right side: 0.400195265 Break this problem into two subproblems by setting (x + 0.8125) equal to 0.400195265 and -0.400195265.Subproblem 1
x + 0.8125 = 0.400195265 Simplifying x + 0.8125 = 0.400195265 Reorder the terms: 0.8125 + x = 0.400195265 Solving 0.8125 + x = 0.400195265 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.8125' to each side of the equation. 0.8125 + -0.8125 + x = 0.400195265 + -0.8125 Combine like terms: 0.8125 + -0.8125 = 0.0000 0.0000 + x = 0.400195265 + -0.8125 x = 0.400195265 + -0.8125 Combine like terms: 0.400195265 + -0.8125 = -0.412304735 x = -0.412304735 Simplifying x = -0.412304735Subproblem 2
x + 0.8125 = -0.400195265 Simplifying x + 0.8125 = -0.400195265 Reorder the terms: 0.8125 + x = -0.400195265 Solving 0.8125 + x = -0.400195265 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.8125' to each side of the equation. 0.8125 + -0.8125 + x = -0.400195265 + -0.8125 Combine like terms: 0.8125 + -0.8125 = 0.0000 0.0000 + x = -0.400195265 + -0.8125 x = -0.400195265 + -0.8125 Combine like terms: -0.400195265 + -0.8125 = -1.212695265 x = -1.212695265 Simplifying x = -1.212695265Solution
The solution to the problem is based on the solutions from the subproblems. x = {-0.412304735, -1.212695265}
