Simplifying x2 + 11x + -86 = 0 Reorder the terms: -86 + 11x + x2 = 0 Solving -86 + 11x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '86' to each side of the equation. -86 + 11x + 86 + x2 = 0 + 86 Reorder the terms: -86 + 86 + 11x + x2 = 0 + 86 Combine like terms: -86 + 86 = 0 0 + 11x + x2 = 0 + 86 11x + x2 = 0 + 86 Combine like terms: 0 + 86 = 86 11x + x2 = 86 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 = 86 + 30.25 Reorder the terms: 30.25 + 11x + x2 = 86 + 30.25 Combine like terms: 86 + 30.25 = 116.25 30.25 + 11x + x2 = 116.25 Factor a perfect square on the left side: (x + 5.5)(x + 5.5) = 116.25 Calculate the square root of the right side: 10.781929326 Break this problem into two subproblems by setting (x + 5.5) equal to 10.781929326 and -10.781929326.Subproblem 1
x + 5.5 = 10.781929326 Simplifying x + 5.5 = 10.781929326 Reorder the terms: 5.5 + x = 10.781929326 Solving 5.5 + x = 10.781929326 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 = 10.781929326 + -5.5 Combine like terms: 5.5 + -5.5 = 0.0 0.0 + x = 10.781929326 + -5.5 x = 10.781929326 + -5.5 Combine like terms: 10.781929326 + -5.5 = 5.281929326 x = 5.281929326 Simplifying x = 5.281929326Subproblem 2
x + 5.5 = -10.781929326 Simplifying x + 5.5 = -10.781929326 Reorder the terms: 5.5 + x = -10.781929326 Solving 5.5 + x = -10.781929326 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 = -10.781929326 + -5.5 Combine like terms: 5.5 + -5.5 = 0.0 0.0 + x = -10.781929326 + -5.5 x = -10.781929326 + -5.5 Combine like terms: -10.781929326 + -5.5 = -16.281929326 x = -16.281929326 Simplifying x = -16.281929326Solution
The solution to the problem is based on the solutions from the subproblems. x = {5.281929326, -16.281929326}
