Simplifying x2 + -1x = 1.75 Reorder the terms: -1x + x2 = 1.75 Solving -1x + x2 = 1.75 Solving for variable 'x'. Reorder the terms: -1.75 + -1x + x2 = 1.75 + -1.75 Combine like terms: 1.75 + -1.75 = 0.00 -1.75 + -1x + x2 = 0.00 Begin completing the square. Move the constant term to the right: Add '1.75' to each side of the equation. -1.75 + -1x + 1.75 + x2 = 0.00 + 1.75 Reorder the terms: -1.75 + 1.75 + -1x + x2 = 0.00 + 1.75 Combine like terms: -1.75 + 1.75 = 0.00 0.00 + -1x + x2 = 0.00 + 1.75 -1x + x2 = 0.00 + 1.75 Combine like terms: 0.00 + 1.75 = 1.75 -1x + x2 = 1.75 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 = 1.75 + 0.25 Reorder the terms: 0.25 + -1x + x2 = 1.75 + 0.25 Combine like terms: 1.75 + 0.25 = 2 0.25 + -1x + x2 = 2 Factor a perfect square on the left side: (x + -0.5)(x + -0.5) = 2 Calculate the square root of the right side: 1.414213562 Break this problem into two subproblems by setting (x + -0.5) equal to 1.414213562 and -1.414213562.Subproblem 1
x + -0.5 = 1.414213562 Simplifying x + -0.5 = 1.414213562 Reorder the terms: -0.5 + x = 1.414213562 Solving -0.5 + x = 1.414213562 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 = 1.414213562 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + x = 1.414213562 + 0.5 x = 1.414213562 + 0.5 Combine like terms: 1.414213562 + 0.5 = 1.914213562 x = 1.914213562 Simplifying x = 1.914213562Subproblem 2
x + -0.5 = -1.414213562 Simplifying x + -0.5 = -1.414213562 Reorder the terms: -0.5 + x = -1.414213562 Solving -0.5 + x = -1.414213562 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 = -1.414213562 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + x = -1.414213562 + 0.5 x = -1.414213562 + 0.5 Combine like terms: -1.414213562 + 0.5 = -0.914213562 x = -0.914213562 Simplifying x = -0.914213562Solution
The solution to the problem is based on the solutions from the subproblems. x = {1.914213562, -0.914213562}
