Simplifying x2 + 27x + 63 = 0 Reorder the terms: 63 + 27x + x2 = 0 Solving 63 + 27x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-63' to each side of the equation. 63 + 27x + -63 + x2 = 0 + -63 Reorder the terms: 63 + -63 + 27x + x2 = 0 + -63 Combine like terms: 63 + -63 = 0 0 + 27x + x2 = 0 + -63 27x + x2 = 0 + -63 Combine like terms: 0 + -63 = -63 27x + x2 = -63 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 = -63 + 182.25 Reorder the terms: 182.25 + 27x + x2 = -63 + 182.25 Combine like terms: -63 + 182.25 = 119.25 182.25 + 27x + x2 = 119.25 Factor a perfect square on the left side: (x + 13.5)(x + 13.5) = 119.25 Calculate the square root of the right side: 10.920164834 Break this problem into two subproblems by setting (x + 13.5) equal to 10.920164834 and -10.920164834.Subproblem 1
x + 13.5 = 10.920164834 Simplifying x + 13.5 = 10.920164834 Reorder the terms: 13.5 + x = 10.920164834 Solving 13.5 + x = 10.920164834 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 = 10.920164834 + -13.5 Combine like terms: 13.5 + -13.5 = 0.0 0.0 + x = 10.920164834 + -13.5 x = 10.920164834 + -13.5 Combine like terms: 10.920164834 + -13.5 = -2.579835166 x = -2.579835166 Simplifying x = -2.579835166Subproblem 2
x + 13.5 = -10.920164834 Simplifying x + 13.5 = -10.920164834 Reorder the terms: 13.5 + x = -10.920164834 Solving 13.5 + x = -10.920164834 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 = -10.920164834 + -13.5 Combine like terms: 13.5 + -13.5 = 0.0 0.0 + x = -10.920164834 + -13.5 x = -10.920164834 + -13.5 Combine like terms: -10.920164834 + -13.5 = -24.420164834 x = -24.420164834 Simplifying x = -24.420164834Solution
The solution to the problem is based on the solutions from the subproblems. x = {-2.579835166, -24.420164834}
