Simplifying x2 + 17x + 27 = 0 Reorder the terms: 27 + 17x + x2 = 0 Solving 27 + 17x + 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 + 17x + -27 + x2 = 0 + -27 Reorder the terms: 27 + -27 + 17x + x2 = 0 + -27 Combine like terms: 27 + -27 = 0 0 + 17x + x2 = 0 + -27 17x + x2 = 0 + -27 Combine like terms: 0 + -27 = -27 17x + x2 = -27 The x term is 17x. Take half its coefficient (8.5). Square it (72.25) and add it to both sides. Add '72.25' to each side of the equation. 17x + 72.25 + x2 = -27 + 72.25 Reorder the terms: 72.25 + 17x + x2 = -27 + 72.25 Combine like terms: -27 + 72.25 = 45.25 72.25 + 17x + x2 = 45.25 Factor a perfect square on the left side: (x + 8.5)(x + 8.5) = 45.25 Calculate the square root of the right side: 6.726812024 Break this problem into two subproblems by setting (x + 8.5) equal to 6.726812024 and -6.726812024.Subproblem 1
x + 8.5 = 6.726812024 Simplifying x + 8.5 = 6.726812024 Reorder the terms: 8.5 + x = 6.726812024 Solving 8.5 + x = 6.726812024 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-8.5' to each side of the equation. 8.5 + -8.5 + x = 6.726812024 + -8.5 Combine like terms: 8.5 + -8.5 = 0.0 0.0 + x = 6.726812024 + -8.5 x = 6.726812024 + -8.5 Combine like terms: 6.726812024 + -8.5 = -1.773187976 x = -1.773187976 Simplifying x = -1.773187976Subproblem 2
x + 8.5 = -6.726812024 Simplifying x + 8.5 = -6.726812024 Reorder the terms: 8.5 + x = -6.726812024 Solving 8.5 + x = -6.726812024 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-8.5' to each side of the equation. 8.5 + -8.5 + x = -6.726812024 + -8.5 Combine like terms: 8.5 + -8.5 = 0.0 0.0 + x = -6.726812024 + -8.5 x = -6.726812024 + -8.5 Combine like terms: -6.726812024 + -8.5 = -15.226812024 x = -15.226812024 Simplifying x = -15.226812024Solution
The solution to the problem is based on the solutions from the subproblems. x = {-1.773187976, -15.226812024}
