Simplifying x2 + -2x + 1 = 81 + -1x Reorder the terms: 1 + -2x + x2 = 81 + -1x Solving 1 + -2x + x2 = 81 + -1x Solving for variable 'x'. Reorder the terms: 1 + -81 + -2x + x + x2 = 81 + -1x + -81 + x Combine like terms: 1 + -81 = -80 -80 + -2x + x + x2 = 81 + -1x + -81 + x Combine like terms: -2x + x = -1x -80 + -1x + x2 = 81 + -1x + -81 + x Reorder the terms: -80 + -1x + x2 = 81 + -81 + -1x + x Combine like terms: 81 + -81 = 0 -80 + -1x + x2 = 0 + -1x + x -80 + -1x + x2 = -1x + x Combine like terms: -1x + x = 0 -80 + -1x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '80' to each side of the equation. -80 + -1x + 80 + x2 = 0 + 80 Reorder the terms: -80 + 80 + -1x + x2 = 0 + 80 Combine like terms: -80 + 80 = 0 0 + -1x + x2 = 0 + 80 -1x + x2 = 0 + 80 Combine like terms: 0 + 80 = 80 -1x + x2 = 80 The x term is -1x. Take half its coefficient (-0.5). Square it (0.25) and add it to both sides. Add '0.25' to each side of the equation. -1x + 0.25 + x2 = 80 + 0.25 Reorder the terms: 0.25 + -1x + x2 = 80 + 0.25 Combine like terms: 80 + 0.25 = 80.25 0.25 + -1x + x2 = 80.25 Factor a perfect square on the left side: (x + -0.5)(x + -0.5) = 80.25 Calculate the square root of the right side: 8.958236434 Break this problem into two subproblems by setting (x + -0.5) equal to 8.958236434 and -8.958236434.Subproblem 1
x + -0.5 = 8.958236434 Simplifying x + -0.5 = 8.958236434 Reorder the terms: -0.5 + x = 8.958236434 Solving -0.5 + x = 8.958236434 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.5' to each side of the equation. -0.5 + 0.5 + x = 8.958236434 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + x = 8.958236434 + 0.5 x = 8.958236434 + 0.5 Combine like terms: 8.958236434 + 0.5 = 9.458236434 x = 9.458236434 Simplifying x = 9.458236434Subproblem 2
x + -0.5 = -8.958236434 Simplifying x + -0.5 = -8.958236434 Reorder the terms: -0.5 + x = -8.958236434 Solving -0.5 + x = -8.958236434 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.5' to each side of the equation. -0.5 + 0.5 + x = -8.958236434 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + x = -8.958236434 + 0.5 x = -8.958236434 + 0.5 Combine like terms: -8.958236434 + 0.5 = -8.458236434 x = -8.458236434 Simplifying x = -8.458236434Solution
The solution to the problem is based on the solutions from the subproblems. x = {9.458236434, -8.458236434}
