Simplifying x2 + 26x + 27 = 0 Reorder the terms: 27 + 26x + x2 = 0 Solving 27 + 26x + 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 + 26x + -27 + x2 = 0 + -27 Reorder the terms: 27 + -27 + 26x + x2 = 0 + -27 Combine like terms: 27 + -27 = 0 0 + 26x + x2 = 0 + -27 26x + x2 = 0 + -27 Combine like terms: 0 + -27 = -27 26x + x2 = -27 The x term is 26x. Take half its coefficient (13). Square it (169) and add it to both sides. Add '169' to each side of the equation. 26x + 169 + x2 = -27 + 169 Reorder the terms: 169 + 26x + x2 = -27 + 169 Combine like terms: -27 + 169 = 142 169 + 26x + x2 = 142 Factor a perfect square on the left side: (x + 13)(x + 13) = 142 Calculate the square root of the right side: 11.916375288 Break this problem into two subproblems by setting (x + 13) equal to 11.916375288 and -11.916375288.Subproblem 1
x + 13 = 11.916375288 Simplifying x + 13 = 11.916375288 Reorder the terms: 13 + x = 11.916375288 Solving 13 + x = 11.916375288 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-13' to each side of the equation. 13 + -13 + x = 11.916375288 + -13 Combine like terms: 13 + -13 = 0 0 + x = 11.916375288 + -13 x = 11.916375288 + -13 Combine like terms: 11.916375288 + -13 = -1.083624712 x = -1.083624712 Simplifying x = -1.083624712Subproblem 2
x + 13 = -11.916375288 Simplifying x + 13 = -11.916375288 Reorder the terms: 13 + x = -11.916375288 Solving 13 + x = -11.916375288 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-13' to each side of the equation. 13 + -13 + x = -11.916375288 + -13 Combine like terms: 13 + -13 = 0 0 + x = -11.916375288 + -13 x = -11.916375288 + -13 Combine like terms: -11.916375288 + -13 = -24.916375288 x = -24.916375288 Simplifying x = -24.916375288Solution
The solution to the problem is based on the solutions from the subproblems. x = {-1.083624712, -24.916375288}
