Simplifying (x + 6)(x + 8) = 129 Reorder the terms: (6 + x)(x + 8) = 129 Reorder the terms: (6 + x)(8 + x) = 129 Multiply (6 + x) * (8 + x) (6(8 + x) + x(8 + x)) = 129 ((8 * 6 + x * 6) + x(8 + x)) = 129 ((48 + 6x) + x(8 + x)) = 129 (48 + 6x + (8 * x + x * x)) = 129 (48 + 6x + (8x + x2)) = 129 Combine like terms: 6x + 8x = 14x (48 + 14x + x2) = 129 Solving 48 + 14x + x2 = 129 Solving for variable 'x'. Reorder the terms: 48 + -129 + 14x + x2 = 129 + -129 Combine like terms: 48 + -129 = -81 -81 + 14x + x2 = 129 + -129 Combine like terms: 129 + -129 = 0 -81 + 14x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '81' to each side of the equation. -81 + 14x + 81 + x2 = 0 + 81 Reorder the terms: -81 + 81 + 14x + x2 = 0 + 81 Combine like terms: -81 + 81 = 0 0 + 14x + x2 = 0 + 81 14x + x2 = 0 + 81 Combine like terms: 0 + 81 = 81 14x + x2 = 81 The x term is 14x. Take half its coefficient (7). Square it (49) and add it to both sides. Add '49' to each side of the equation. 14x + 49 + x2 = 81 + 49 Reorder the terms: 49 + 14x + x2 = 81 + 49 Combine like terms: 81 + 49 = 130 49 + 14x + x2 = 130 Factor a perfect square on the left side: (x + 7)(x + 7) = 130 Calculate the square root of the right side: 11.401754251 Break this problem into two subproblems by setting (x + 7) equal to 11.401754251 and -11.401754251.Subproblem 1
x + 7 = 11.401754251 Simplifying x + 7 = 11.401754251 Reorder the terms: 7 + x = 11.401754251 Solving 7 + x = 11.401754251 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-7' to each side of the equation. 7 + -7 + x = 11.401754251 + -7 Combine like terms: 7 + -7 = 0 0 + x = 11.401754251 + -7 x = 11.401754251 + -7 Combine like terms: 11.401754251 + -7 = 4.401754251 x = 4.401754251 Simplifying x = 4.401754251Subproblem 2
x + 7 = -11.401754251 Simplifying x + 7 = -11.401754251 Reorder the terms: 7 + x = -11.401754251 Solving 7 + x = -11.401754251 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-7' to each side of the equation. 7 + -7 + x = -11.401754251 + -7 Combine like terms: 7 + -7 = 0 0 + x = -11.401754251 + -7 x = -11.401754251 + -7 Combine like terms: -11.401754251 + -7 = -18.401754251 x = -18.401754251 Simplifying x = -18.401754251Solution
The solution to the problem is based on the solutions from the subproblems. x = {4.401754251, -18.401754251}
