Simplifying 8x2 + -19x + -648 = 0 Reorder the terms: -648 + -19x + 8x2 = 0 Solving -648 + -19x + 8x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 8 the coefficient of the squared term: Divide each side by '8'. -81 + -2.375x + x2 = 0 Move the constant term to the right: Add '81' to each side of the equation. -81 + -2.375x + 81 + x2 = 0 + 81 Reorder the terms: -81 + 81 + -2.375x + x2 = 0 + 81 Combine like terms: -81 + 81 = 0 0 + -2.375x + x2 = 0 + 81 -2.375x + x2 = 0 + 81 Combine like terms: 0 + 81 = 81 -2.375x + x2 = 81 The x term is -2.375x. Take half its coefficient (-1.1875). Square it (1.41015625) and add it to both sides. Add '1.41015625' to each side of the equation. -2.375x + 1.41015625 + x2 = 81 + 1.41015625 Reorder the terms: 1.41015625 + -2.375x + x2 = 81 + 1.41015625 Combine like terms: 81 + 1.41015625 = 82.41015625 1.41015625 + -2.375x + x2 = 82.41015625 Factor a perfect square on the left side: (x + -1.1875)(x + -1.1875) = 82.41015625 Calculate the square root of the right side: 9.078003979 Break this problem into two subproblems by setting (x + -1.1875) equal to 9.078003979 and -9.078003979.Subproblem 1
x + -1.1875 = 9.078003979 Simplifying x + -1.1875 = 9.078003979 Reorder the terms: -1.1875 + x = 9.078003979 Solving -1.1875 + x = 9.078003979 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1.1875' to each side of the equation. -1.1875 + 1.1875 + x = 9.078003979 + 1.1875 Combine like terms: -1.1875 + 1.1875 = 0.0000 0.0000 + x = 9.078003979 + 1.1875 x = 9.078003979 + 1.1875 Combine like terms: 9.078003979 + 1.1875 = 10.265503979 x = 10.265503979 Simplifying x = 10.265503979Subproblem 2
x + -1.1875 = -9.078003979 Simplifying x + -1.1875 = -9.078003979 Reorder the terms: -1.1875 + x = -9.078003979 Solving -1.1875 + x = -9.078003979 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1.1875' to each side of the equation. -1.1875 + 1.1875 + x = -9.078003979 + 1.1875 Combine like terms: -1.1875 + 1.1875 = 0.0000 0.0000 + x = -9.078003979 + 1.1875 x = -9.078003979 + 1.1875 Combine like terms: -9.078003979 + 1.1875 = -7.890503979 x = -7.890503979 Simplifying x = -7.890503979Solution
The solution to the problem is based on the solutions from the subproblems. x = {10.265503979, -7.890503979}
