Simplifying 8x2 + 6x + -19 = 0 Reorder the terms: -19 + 6x + 8x2 = 0 Solving -19 + 6x + 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'. -2.375 + 0.75x + x2 = 0 Move the constant term to the right: Add '2.375' to each side of the equation. -2.375 + 0.75x + 2.375 + x2 = 0 + 2.375 Reorder the terms: -2.375 + 2.375 + 0.75x + x2 = 0 + 2.375 Combine like terms: -2.375 + 2.375 = 0.000 0.000 + 0.75x + x2 = 0 + 2.375 0.75x + x2 = 0 + 2.375 Combine like terms: 0 + 2.375 = 2.375 0.75x + x2 = 2.375 The x term is 0.75x. Take half its coefficient (0.375). Square it (0.140625) and add it to both sides. Add '0.140625' to each side of the equation. 0.75x + 0.140625 + x2 = 2.375 + 0.140625 Reorder the terms: 0.140625 + 0.75x + x2 = 2.375 + 0.140625 Combine like terms: 2.375 + 0.140625 = 2.515625 0.140625 + 0.75x + x2 = 2.515625 Factor a perfect square on the left side: (x + 0.375)(x + 0.375) = 2.515625 Calculate the square root of the right side: 1.586072193 Break this problem into two subproblems by setting (x + 0.375) equal to 1.586072193 and -1.586072193.Subproblem 1
x + 0.375 = 1.586072193 Simplifying x + 0.375 = 1.586072193 Reorder the terms: 0.375 + x = 1.586072193 Solving 0.375 + x = 1.586072193 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.375' to each side of the equation. 0.375 + -0.375 + x = 1.586072193 + -0.375 Combine like terms: 0.375 + -0.375 = 0.000 0.000 + x = 1.586072193 + -0.375 x = 1.586072193 + -0.375 Combine like terms: 1.586072193 + -0.375 = 1.211072193 x = 1.211072193 Simplifying x = 1.211072193Subproblem 2
x + 0.375 = -1.586072193 Simplifying x + 0.375 = -1.586072193 Reorder the terms: 0.375 + x = -1.586072193 Solving 0.375 + x = -1.586072193 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.375' to each side of the equation. 0.375 + -0.375 + x = -1.586072193 + -0.375 Combine like terms: 0.375 + -0.375 = 0.000 0.000 + x = -1.586072193 + -0.375 x = -1.586072193 + -0.375 Combine like terms: -1.586072193 + -0.375 = -1.961072193 x = -1.961072193 Simplifying x = -1.961072193Solution
