Simplifying x(x + -1) = 142 Reorder the terms: x(-1 + x) = 142 (-1 * x + x * x) = 142 (-1x + x2) = 142 Solving -1x + x2 = 142 Solving for variable 'x'. Reorder the terms: -142 + -1x + x2 = 142 + -142 Combine like terms: 142 + -142 = 0 -142 + -1x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '142' to each side of the equation. -142 + -1x + 142 + x2 = 0 + 142 Reorder the terms: -142 + 142 + -1x + x2 = 0 + 142 Combine like terms: -142 + 142 = 0 0 + -1x + x2 = 0 + 142 -1x + x2 = 0 + 142 Combine like terms: 0 + 142 = 142 -1x + x2 = 142 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 = 142 + 0.25 Reorder the terms: 0.25 + -1x + x2 = 142 + 0.25 Combine like terms: 142 + 0.25 = 142.25 0.25 + -1x + x2 = 142.25 Factor a perfect square on the left side: (x + -0.5)(x + -0.5) = 142.25 Calculate the square root of the right side: 11.926860442 Break this problem into two subproblems by setting (x + -0.5) equal to 11.926860442 and -11.926860442.Subproblem 1
x + -0.5 = 11.926860442 Simplifying x + -0.5 = 11.926860442 Reorder the terms: -0.5 + x = 11.926860442 Solving -0.5 + x = 11.926860442 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 = 11.926860442 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + x = 11.926860442 + 0.5 x = 11.926860442 + 0.5 Combine like terms: 11.926860442 + 0.5 = 12.426860442 x = 12.426860442 Simplifying x = 12.426860442Subproblem 2
x + -0.5 = -11.926860442 Simplifying x + -0.5 = -11.926860442 Reorder the terms: -0.5 + x = -11.926860442 Solving -0.5 + x = -11.926860442 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 = -11.926860442 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + x = -11.926860442 + 0.5 x = -11.926860442 + 0.5 Combine like terms: -11.926860442 + 0.5 = -11.426860442 x = -11.426860442 Simplifying x = -11.426860442Solution
The solution to the problem is based on the solutions from the subproblems. x = {12.426860442, -11.426860442}
