Simplifying 3x2 + -3x + -248 = 0 Reorder the terms: -248 + -3x + 3x2 = 0 Solving -248 + -3x + 3x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 3 the coefficient of the squared term: Divide each side by '3'. -82.66666667 + -1x + x2 = 0 Move the constant term to the right: Add '82.66666667' to each side of the equation. -82.66666667 + -1x + 82.66666667 + x2 = 0 + 82.66666667 Reorder the terms: -82.66666667 + 82.66666667 + -1x + x2 = 0 + 82.66666667 Combine like terms: -82.66666667 + 82.66666667 = 0.00000000 0.00000000 + -1x + x2 = 0 + 82.66666667 -1x + x2 = 0 + 82.66666667 Combine like terms: 0 + 82.66666667 = 82.66666667 -1x + x2 = 82.66666667 The x term is -1x. Take half its coefficient (-0.5). Square it (0.25) and add it to both sides. Add '0.25' to each side of the equation. -1x + 0.25 + x2 = 82.66666667 + 0.25 Reorder the terms: 0.25 + -1x + x2 = 82.66666667 + 0.25 Combine like terms: 82.66666667 + 0.25 = 82.91666667 0.25 + -1x + x2 = 82.91666667 Factor a perfect square on the left side: (x + -0.5)(x + -0.5) = 82.91666667 Calculate the square root of the right side: 9.10585892 Break this problem into two subproblems by setting (x + -0.5) equal to 9.10585892 and -9.10585892.Subproblem 1
x + -0.5 = 9.10585892 Simplifying x + -0.5 = 9.10585892 Reorder the terms: -0.5 + x = 9.10585892 Solving -0.5 + x = 9.10585892 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.5' to each side of the equation. -0.5 + 0.5 + x = 9.10585892 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + x = 9.10585892 + 0.5 x = 9.10585892 + 0.5 Combine like terms: 9.10585892 + 0.5 = 9.60585892 x = 9.60585892 Simplifying x = 9.60585892Subproblem 2
x + -0.5 = -9.10585892 Simplifying x + -0.5 = -9.10585892 Reorder the terms: -0.5 + x = -9.10585892 Solving -0.5 + x = -9.10585892 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.5' to each side of the equation. -0.5 + 0.5 + x = -9.10585892 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + x = -9.10585892 + 0.5 x = -9.10585892 + 0.5 Combine like terms: -9.10585892 + 0.5 = -8.60585892 x = -8.60585892 Simplifying x = -8.60585892Solution
The solution to the problem is based on the solutions from the subproblems. x = {9.60585892, -8.60585892}
