Simplifying x2 + x + -126 = 0 Reorder the terms: -126 + x + x2 = 0 Solving -126 + x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '126' to each side of the equation. -126 + x + 126 + x2 = 0 + 126 Reorder the terms: -126 + 126 + x + x2 = 0 + 126 Combine like terms: -126 + 126 = 0 0 + x + x2 = 0 + 126 x + x2 = 0 + 126 Combine like terms: 0 + 126 = 126 x + x2 = 126 The x term is x. 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. x + 0.25 + x2 = 126 + 0.25 Reorder the terms: 0.25 + x + x2 = 126 + 0.25 Combine like terms: 126 + 0.25 = 126.25 0.25 + x + x2 = 126.25 Factor a perfect square on the left side: (x + 0.5)(x + 0.5) = 126.25 Calculate the square root of the right side: 11.236102527 Break this problem into two subproblems by setting (x + 0.5) equal to 11.236102527 and -11.236102527.Subproblem 1
x + 0.5 = 11.236102527 Simplifying x + 0.5 = 11.236102527 Reorder the terms: 0.5 + x = 11.236102527 Solving 0.5 + x = 11.236102527 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 = 11.236102527 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + x = 11.236102527 + -0.5 x = 11.236102527 + -0.5 Combine like terms: 11.236102527 + -0.5 = 10.736102527 x = 10.736102527 Simplifying x = 10.736102527Subproblem 2
x + 0.5 = -11.236102527 Simplifying x + 0.5 = -11.236102527 Reorder the terms: 0.5 + x = -11.236102527 Solving 0.5 + x = -11.236102527 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 = -11.236102527 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + x = -11.236102527 + -0.5 x = -11.236102527 + -0.5 Combine like terms: -11.236102527 + -0.5 = -11.736102527 x = -11.736102527 Simplifying x = -11.736102527Solution
The solution to the problem is based on the solutions from the subproblems. x = {10.736102527, -11.736102527}
