Simplifying x(x + 2) = 139 Reorder the terms: x(2 + x) = 139 (2 * x + x * x) = 139 (2x + x2) = 139 Solving 2x + x2 = 139 Solving for variable 'x'. Reorder the terms: -139 + 2x + x2 = 139 + -139 Combine like terms: 139 + -139 = 0 -139 + 2x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '139' to each side of the equation. -139 + 2x + 139 + x2 = 0 + 139 Reorder the terms: -139 + 139 + 2x + x2 = 0 + 139 Combine like terms: -139 + 139 = 0 0 + 2x + x2 = 0 + 139 2x + x2 = 0 + 139 Combine like terms: 0 + 139 = 139 2x + x2 = 139 The x term is 2x. Take half its coefficient (1). Square it (1) and add it to both sides. Add '1' to each side of the equation. 2x + 1 + x2 = 139 + 1 Reorder the terms: 1 + 2x + x2 = 139 + 1 Combine like terms: 139 + 1 = 140 1 + 2x + x2 = 140 Factor a perfect square on the left side: (x + 1)(x + 1) = 140 Calculate the square root of the right side: 11.832159566 Break this problem into two subproblems by setting (x + 1) equal to 11.832159566 and -11.832159566.Subproblem 1
x + 1 = 11.832159566 Simplifying x + 1 = 11.832159566 Reorder the terms: 1 + x = 11.832159566 Solving 1 + x = 11.832159566 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + x = 11.832159566 + -1 Combine like terms: 1 + -1 = 0 0 + x = 11.832159566 + -1 x = 11.832159566 + -1 Combine like terms: 11.832159566 + -1 = 10.832159566 x = 10.832159566 Simplifying x = 10.832159566Subproblem 2
x + 1 = -11.832159566 Simplifying x + 1 = -11.832159566 Reorder the terms: 1 + x = -11.832159566 Solving 1 + x = -11.832159566 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + x = -11.832159566 + -1 Combine like terms: 1 + -1 = 0 0 + x = -11.832159566 + -1 x = -11.832159566 + -1 Combine like terms: -11.832159566 + -1 = -12.832159566 x = -12.832159566 Simplifying x = -12.832159566Solution
The solution to the problem is based on the solutions from the subproblems. x = {10.832159566, -12.832159566}
