Simplifying x2 + 17x + 56 = 0 Reorder the terms: 56 + 17x + x2 = 0 Solving 56 + 17x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-56' to each side of the equation. 56 + 17x + -56 + x2 = 0 + -56 Reorder the terms: 56 + -56 + 17x + x2 = 0 + -56 Combine like terms: 56 + -56 = 0 0 + 17x + x2 = 0 + -56 17x + x2 = 0 + -56 Combine like terms: 0 + -56 = -56 17x + x2 = -56 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 = -56 + 72.25 Reorder the terms: 72.25 + 17x + x2 = -56 + 72.25 Combine like terms: -56 + 72.25 = 16.25 72.25 + 17x + x2 = 16.25 Factor a perfect square on the left side: (x + 8.5)(x + 8.5) = 16.25 Calculate the square root of the right side: 4.031128874 Break this problem into two subproblems by setting (x + 8.5) equal to 4.031128874 and -4.031128874.Subproblem 1
x + 8.5 = 4.031128874 Simplifying x + 8.5 = 4.031128874 Reorder the terms: 8.5 + x = 4.031128874 Solving 8.5 + x = 4.031128874 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 = 4.031128874 + -8.5 Combine like terms: 8.5 + -8.5 = 0.0 0.0 + x = 4.031128874 + -8.5 x = 4.031128874 + -8.5 Combine like terms: 4.031128874 + -8.5 = -4.468871126 x = -4.468871126 Simplifying x = -4.468871126Subproblem 2
x + 8.5 = -4.031128874 Simplifying x + 8.5 = -4.031128874 Reorder the terms: 8.5 + x = -4.031128874 Solving 8.5 + x = -4.031128874 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 = -4.031128874 + -8.5 Combine like terms: 8.5 + -8.5 = 0.0 0.0 + x = -4.031128874 + -8.5 x = -4.031128874 + -8.5 Combine like terms: -4.031128874 + -8.5 = -12.531128874 x = -12.531128874 Simplifying x = -12.531128874Solution
The solution to the problem is based on the solutions from the subproblems. x = {-4.468871126, -12.531128874}
