Simplifying x2 + -1x + -2(-1x + 0.5) + -62 = 0 Reorder the terms: x2 + -1x + -2(0.5 + -1x) + -62 = 0 x2 + -1x + (0.5 * -2 + -1x * -2) + -62 = 0 x2 + -1x + (-1 + 2x) + -62 = 0 Reorder the terms: -1 + -62 + -1x + 2x + x2 = 0 Combine like terms: -1 + -62 = -63 -63 + -1x + 2x + x2 = 0 Combine like terms: -1x + 2x = 1x -63 + 1x + x2 = 0 Solving -63 + 1x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '63' to each side of the equation. -63 + 1x + 63 + x2 = 0 + 63 Reorder the terms: -63 + 63 + 1x + x2 = 0 + 63 Combine like terms: -63 + 63 = 0 0 + 1x + x2 = 0 + 63 1x + x2 = 0 + 63 Combine like terms: 0 + 63 = 63 1x + x2 = 63 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. x + 0.25 + x2 = 63 + 0.25 Reorder the terms: 0.25 + x + x2 = 63 + 0.25 Combine like terms: 63 + 0.25 = 63.25 0.25 + x + x2 = 63.25 Factor a perfect square on the left side: (x + 0.5)(x + 0.5) = 63.25 Calculate the square root of the right side: 7.95298686 Break this problem into two subproblems by setting (x + 0.5) equal to 7.95298686 and -7.95298686.Subproblem 1
x + 0.5 = 7.95298686 Simplifying x + 0.5 = 7.95298686 Reorder the terms: 0.5 + x = 7.95298686 Solving 0.5 + x = 7.95298686 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 = 7.95298686 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + x = 7.95298686 + -0.5 x = 7.95298686 + -0.5 Combine like terms: 7.95298686 + -0.5 = 7.45298686 x = 7.45298686 Simplifying x = 7.45298686Subproblem 2
x + 0.5 = -7.95298686 Simplifying x + 0.5 = -7.95298686 Reorder the terms: 0.5 + x = -7.95298686 Solving 0.5 + x = -7.95298686 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 = -7.95298686 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + x = -7.95298686 + -0.5 x = -7.95298686 + -0.5 Combine like terms: -7.95298686 + -0.5 = -8.45298686 x = -8.45298686 Simplifying x = -8.45298686Solution
The solution to the problem is based on the solutions from the subproblems. x = {7.45298686, -8.45298686}
