Simplifying x2 + 11x + 27 = 0 Reorder the terms: 27 + 11x + x2 = 0 Solving 27 + 11x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-27' to each side of the equation. 27 + 11x + -27 + x2 = 0 + -27 Reorder the terms: 27 + -27 + 11x + x2 = 0 + -27 Combine like terms: 27 + -27 = 0 0 + 11x + x2 = 0 + -27 11x + x2 = 0 + -27 Combine like terms: 0 + -27 = -27 11x + x2 = -27 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 = -27 + 30.25 Reorder the terms: 30.25 + 11x + x2 = -27 + 30.25 Combine like terms: -27 + 30.25 = 3.25 30.25 + 11x + x2 = 3.25 Factor a perfect square on the left side: (x + 5.5)(x + 5.5) = 3.25 Calculate the square root of the right side: 1.802775638 Break this problem into two subproblems by setting (x + 5.5) equal to 1.802775638 and -1.802775638.Subproblem 1
x + 5.5 = 1.802775638 Simplifying x + 5.5 = 1.802775638 Reorder the terms: 5.5 + x = 1.802775638 Solving 5.5 + x = 1.802775638 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 = 1.802775638 + -5.5 Combine like terms: 5.5 + -5.5 = 0.0 0.0 + x = 1.802775638 + -5.5 x = 1.802775638 + -5.5 Combine like terms: 1.802775638 + -5.5 = -3.697224362 x = -3.697224362 Simplifying x = -3.697224362Subproblem 2
x + 5.5 = -1.802775638 Simplifying x + 5.5 = -1.802775638 Reorder the terms: 5.5 + x = -1.802775638 Solving 5.5 + x = -1.802775638 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 = -1.802775638 + -5.5 Combine like terms: 5.5 + -5.5 = 0.0 0.0 + x = -1.802775638 + -5.5 x = -1.802775638 + -5.5 Combine like terms: -1.802775638 + -5.5 = -7.302775638 x = -7.302775638 Simplifying x = -7.302775638Solution
The solution to the problem is based on the solutions from the subproblems. x = {-3.697224362, -7.302775638}
