Simplifying x2 + -2x + 1 = 9x + 12 Reorder the terms: 1 + -2x + x2 = 9x + 12 Reorder the terms: 1 + -2x + x2 = 12 + 9x Solving 1 + -2x + x2 = 12 + 9x Solving for variable 'x'. Reorder the terms: 1 + -12 + -2x + -9x + x2 = 12 + 9x + -12 + -9x Combine like terms: 1 + -12 = -11 -11 + -2x + -9x + x2 = 12 + 9x + -12 + -9x Combine like terms: -2x + -9x = -11x -11 + -11x + x2 = 12 + 9x + -12 + -9x Reorder the terms: -11 + -11x + x2 = 12 + -12 + 9x + -9x Combine like terms: 12 + -12 = 0 -11 + -11x + x2 = 0 + 9x + -9x -11 + -11x + x2 = 9x + -9x Combine like terms: 9x + -9x = 0 -11 + -11x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '11' to each side of the equation. -11 + -11x + 11 + x2 = 0 + 11 Reorder the terms: -11 + 11 + -11x + x2 = 0 + 11 Combine like terms: -11 + 11 = 0 0 + -11x + x2 = 0 + 11 -11x + x2 = 0 + 11 Combine like terms: 0 + 11 = 11 -11x + x2 = 11 The x term is -11x. Take half its coefficient (-5.5). Square it (30.25) and add it to both sides. Add '30.25' to each side of the equation. -11x + 30.25 + x2 = 11 + 30.25 Reorder the terms: 30.25 + -11x + x2 = 11 + 30.25 Combine like terms: 11 + 30.25 = 41.25 30.25 + -11x + x2 = 41.25 Factor a perfect square on the left side: (x + -5.5)(x + -5.5) = 41.25 Calculate the square root of the right side: 6.422616289 Break this problem into two subproblems by setting (x + -5.5) equal to 6.422616289 and -6.422616289.Subproblem 1
x + -5.5 = 6.422616289 Simplifying x + -5.5 = 6.422616289 Reorder the terms: -5.5 + x = 6.422616289 Solving -5.5 + x = 6.422616289 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '5.5' to each side of the equation. -5.5 + 5.5 + x = 6.422616289 + 5.5 Combine like terms: -5.5 + 5.5 = 0.0 0.0 + x = 6.422616289 + 5.5 x = 6.422616289 + 5.5 Combine like terms: 6.422616289 + 5.5 = 11.922616289 x = 11.922616289 Simplifying x = 11.922616289Subproblem 2
x + -5.5 = -6.422616289 Simplifying x + -5.5 = -6.422616289 Reorder the terms: -5.5 + x = -6.422616289 Solving -5.5 + x = -6.422616289 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '5.5' to each side of the equation. -5.5 + 5.5 + x = -6.422616289 + 5.5 Combine like terms: -5.5 + 5.5 = 0.0 0.0 + x = -6.422616289 + 5.5 x = -6.422616289 + 5.5 Combine like terms: -6.422616289 + 5.5 = -0.922616289 x = -0.922616289 Simplifying x = -0.922616289Solution
The solution to the problem is based on the solutions from the subproblems. x = {11.922616289, -0.922616289}
