Simplifying x(x) + 11x + -1 = 0 Multiply x * x x2 + 11x + -1 = 0 Reorder the terms: -1 + 11x + x2 = 0 Solving -1 + 11x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '1' to each side of the equation. -1 + 11x + 1 + x2 = 0 + 1 Reorder the terms: -1 + 1 + 11x + x2 = 0 + 1 Combine like terms: -1 + 1 = 0 0 + 11x + x2 = 0 + 1 11x + x2 = 0 + 1 Combine like terms: 0 + 1 = 1 11x + x2 = 1 The x term is 11x. Take half its coefficient (5.5). Square it (30.25) and add it to both sides. Add '30.25' to each side of the equation. 11x + 30.25 + x2 = 1 + 30.25 Reorder the terms: 30.25 + 11x + x2 = 1 + 30.25 Combine like terms: 1 + 30.25 = 31.25 30.25 + 11x + x2 = 31.25 Factor a perfect square on the left side: (x + 5.5)(x + 5.5) = 31.25 Calculate the square root of the right side: 5.590169944 Break this problem into two subproblems by setting (x + 5.5) equal to 5.590169944 and -5.590169944.Subproblem 1
x + 5.5 = 5.590169944 Simplifying x + 5.5 = 5.590169944 Reorder the terms: 5.5 + x = 5.590169944 Solving 5.5 + x = 5.590169944 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-5.5' to each side of the equation. 5.5 + -5.5 + x = 5.590169944 + -5.5 Combine like terms: 5.5 + -5.5 = 0.0 0.0 + x = 5.590169944 + -5.5 x = 5.590169944 + -5.5 Combine like terms: 5.590169944 + -5.5 = 0.090169944 x = 0.090169944 Simplifying x = 0.090169944Subproblem 2
x + 5.5 = -5.590169944 Simplifying x + 5.5 = -5.590169944 Reorder the terms: 5.5 + x = -5.590169944 Solving 5.5 + x = -5.590169944 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-5.5' to each side of the equation. 5.5 + -5.5 + x = -5.590169944 + -5.5 Combine like terms: 5.5 + -5.5 = 0.0 0.0 + x = -5.590169944 + -5.5 x = -5.590169944 + -5.5 Combine like terms: -5.590169944 + -5.5 = -11.090169944 x = -11.090169944 Simplifying x = -11.090169944Solution
The solution to the problem is based on the solutions from the subproblems. x = {0.090169944, -11.090169944}
