Simplifying x2 + 11x + 10 = 9 Reorder the terms: 10 + 11x + x2 = 9 Solving 10 + 11x + x2 = 9 Solving for variable 'x'. Reorder the terms: 10 + -9 + 11x + x2 = 9 + -9 Combine like terms: 10 + -9 = 1 1 + 11x + x2 = 9 + -9 Combine like terms: 9 + -9 = 0 1 + 11x + x2 = 0 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 = 29.25 30.25 + 11x + x2 = 29.25 Factor a perfect square on the left side: (x + 5.5)(x + 5.5) = 29.25 Calculate the square root of the right side: 5.408326913 Break this problem into two subproblems by setting (x + 5.5) equal to 5.408326913 and -5.408326913.Subproblem 1
x + 5.5 = 5.408326913 Simplifying x + 5.5 = 5.408326913 Reorder the terms: 5.5 + x = 5.408326913 Solving 5.5 + x = 5.408326913 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 = 5.408326913 + -5.5 Combine like terms: 5.5 + -5.5 = 0.0 0.0 + x = 5.408326913 + -5.5 x = 5.408326913 + -5.5 Combine like terms: 5.408326913 + -5.5 = -0.091673087 x = -0.091673087 Simplifying x = -0.091673087Subproblem 2
x + 5.5 = -5.408326913 Simplifying x + 5.5 = -5.408326913 Reorder the terms: 5.5 + x = -5.408326913 Solving 5.5 + x = -5.408326913 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 = -5.408326913 + -5.5 Combine like terms: 5.5 + -5.5 = 0.0 0.0 + x = -5.408326913 + -5.5 x = -5.408326913 + -5.5 Combine like terms: -5.408326913 + -5.5 = -10.908326913 x = -10.908326913 Simplifying x = -10.908326913Solution
The solution to the problem is based on the solutions from the subproblems. x = {-0.091673087, -10.908326913}
