Simplifying x2 + 11x + 9 = 0 Reorder the terms: 9 + 11x + x2 = 0 Solving 9 + 11x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-9' to each side of the equation. 9 + 11x + -9 + x2 = 0 + -9 Reorder the terms: 9 + -9 + 11x + x2 = 0 + -9 Combine like terms: 9 + -9 = 0 0 + 11x + x2 = 0 + -9 11x + x2 = 0 + -9 Combine like terms: 0 + -9 = -9 11x + x2 = -9 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 = -9 + 30.25 Reorder the terms: 30.25 + 11x + x2 = -9 + 30.25 Combine like terms: -9 + 30.25 = 21.25 30.25 + 11x + x2 = 21.25 Factor a perfect square on the left side: (x + 5.5)(x + 5.5) = 21.25 Calculate the square root of the right side: 4.609772229 Break this problem into two subproblems by setting (x + 5.5) equal to 4.609772229 and -4.609772229.Subproblem 1
x + 5.5 = 4.609772229 Simplifying x + 5.5 = 4.609772229 Reorder the terms: 5.5 + x = 4.609772229 Solving 5.5 + x = 4.609772229 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 = 4.609772229 + -5.5 Combine like terms: 5.5 + -5.5 = 0.0 0.0 + x = 4.609772229 + -5.5 x = 4.609772229 + -5.5 Combine like terms: 4.609772229 + -5.5 = -0.890227771 x = -0.890227771 Simplifying x = -0.890227771Subproblem 2
x + 5.5 = -4.609772229 Simplifying x + 5.5 = -4.609772229 Reorder the terms: 5.5 + x = -4.609772229 Solving 5.5 + x = -4.609772229 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 = -4.609772229 + -5.5 Combine like terms: 5.5 + -5.5 = 0.0 0.0 + x = -4.609772229 + -5.5 x = -4.609772229 + -5.5 Combine like terms: -4.609772229 + -5.5 = -10.109772229 x = -10.109772229 Simplifying x = -10.109772229Solution
The solution to the problem is based on the solutions from the subproblems. x = {-0.890227771, -10.109772229}
