Simplifying x2 + 17x + -10 = 0 Reorder the terms: -10 + 17x + x2 = 0 Solving -10 + 17x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '10' to each side of the equation. -10 + 17x + 10 + x2 = 0 + 10 Reorder the terms: -10 + 10 + 17x + x2 = 0 + 10 Combine like terms: -10 + 10 = 0 0 + 17x + x2 = 0 + 10 17x + x2 = 0 + 10 Combine like terms: 0 + 10 = 10 17x + x2 = 10 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 = 10 + 72.25 Reorder the terms: 72.25 + 17x + x2 = 10 + 72.25 Combine like terms: 10 + 72.25 = 82.25 72.25 + 17x + x2 = 82.25 Factor a perfect square on the left side: (x + 8.5)(x + 8.5) = 82.25 Calculate the square root of the right side: 9.069178574 Break this problem into two subproblems by setting (x + 8.5) equal to 9.069178574 and -9.069178574.Subproblem 1
x + 8.5 = 9.069178574 Simplifying x + 8.5 = 9.069178574 Reorder the terms: 8.5 + x = 9.069178574 Solving 8.5 + x = 9.069178574 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 = 9.069178574 + -8.5 Combine like terms: 8.5 + -8.5 = 0.0 0.0 + x = 9.069178574 + -8.5 x = 9.069178574 + -8.5 Combine like terms: 9.069178574 + -8.5 = 0.569178574 x = 0.569178574 Simplifying x = 0.569178574Subproblem 2
x + 8.5 = -9.069178574 Simplifying x + 8.5 = -9.069178574 Reorder the terms: 8.5 + x = -9.069178574 Solving 8.5 + x = -9.069178574 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 = -9.069178574 + -8.5 Combine like terms: 8.5 + -8.5 = 0.0 0.0 + x = -9.069178574 + -8.5 x = -9.069178574 + -8.5 Combine like terms: -9.069178574 + -8.5 = -17.569178574 x = -17.569178574 Simplifying x = -17.569178574Solution
