Simplifying x2 + 27x + 41 = 0 Reorder the terms: 41 + 27x + x2 = 0 Solving 41 + 27x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-41' to each side of the equation. 41 + 27x + -41 + x2 = 0 + -41 Reorder the terms: 41 + -41 + 27x + x2 = 0 + -41 Combine like terms: 41 + -41 = 0 0 + 27x + x2 = 0 + -41 27x + x2 = 0 + -41 Combine like terms: 0 + -41 = -41 27x + x2 = -41 The x term is 27x. Take half its coefficient (13.5). Square it (182.25) and add it to both sides. Add '182.25' to each side of the equation. 27x + 182.25 + x2 = -41 + 182.25 Reorder the terms: 182.25 + 27x + x2 = -41 + 182.25 Combine like terms: -41 + 182.25 = 141.25 182.25 + 27x + x2 = 141.25 Factor a perfect square on the left side: (x + 13.5)(x + 13.5) = 141.25 Calculate the square root of the right side: 11.884864324 Break this problem into two subproblems by setting (x + 13.5) equal to 11.884864324 and -11.884864324.Subproblem 1
x + 13.5 = 11.884864324 Simplifying x + 13.5 = 11.884864324 Reorder the terms: 13.5 + x = 11.884864324 Solving 13.5 + x = 11.884864324 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-13.5' to each side of the equation. 13.5 + -13.5 + x = 11.884864324 + -13.5 Combine like terms: 13.5 + -13.5 = 0.0 0.0 + x = 11.884864324 + -13.5 x = 11.884864324 + -13.5 Combine like terms: 11.884864324 + -13.5 = -1.615135676 x = -1.615135676 Simplifying x = -1.615135676Subproblem 2
x + 13.5 = -11.884864324 Simplifying x + 13.5 = -11.884864324 Reorder the terms: 13.5 + x = -11.884864324 Solving 13.5 + x = -11.884864324 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-13.5' to each side of the equation. 13.5 + -13.5 + x = -11.884864324 + -13.5 Combine like terms: 13.5 + -13.5 = 0.0 0.0 + x = -11.884864324 + -13.5 x = -11.884864324 + -13.5 Combine like terms: -11.884864324 + -13.5 = -25.384864324 x = -25.384864324 Simplifying x = -25.384864324Solution
The solution to the problem is based on the solutions from the subproblems. x = {-1.615135676, -25.384864324}
