Simplifying (x + 7)(x + 5) = 1 Reorder the terms: (7 + x)(x + 5) = 1 Reorder the terms: (7 + x)(5 + x) = 1 Multiply (7 + x) * (5 + x) (7(5 + x) + x(5 + x)) = 1 ((5 * 7 + x * 7) + x(5 + x)) = 1 ((35 + 7x) + x(5 + x)) = 1 (35 + 7x + (5 * x + x * x)) = 1 (35 + 7x + (5x + x2)) = 1 Combine like terms: 7x + 5x = 12x (35 + 12x + x2) = 1 Solving 35 + 12x + x2 = 1 Solving for variable 'x'. Reorder the terms: 35 + -1 + 12x + x2 = 1 + -1 Combine like terms: 35 + -1 = 34 34 + 12x + x2 = 1 + -1 Combine like terms: 1 + -1 = 0 34 + 12x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-34' to each side of the equation. 34 + 12x + -34 + x2 = 0 + -34 Reorder the terms: 34 + -34 + 12x + x2 = 0 + -34 Combine like terms: 34 + -34 = 0 0 + 12x + x2 = 0 + -34 12x + x2 = 0 + -34 Combine like terms: 0 + -34 = -34 12x + x2 = -34 The x term is 12x. Take half its coefficient (6). Square it (36) and add it to both sides. Add '36' to each side of the equation. 12x + 36 + x2 = -34 + 36 Reorder the terms: 36 + 12x + x2 = -34 + 36 Combine like terms: -34 + 36 = 2 36 + 12x + x2 = 2 Factor a perfect square on the left side: (x + 6)(x + 6) = 2 Calculate the square root of the right side: 1.414213562 Break this problem into two subproblems by setting (x + 6) equal to 1.414213562 and -1.414213562.Subproblem 1
x + 6 = 1.414213562 Simplifying x + 6 = 1.414213562 Reorder the terms: 6 + x = 1.414213562 Solving 6 + x = 1.414213562 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-6' to each side of the equation. 6 + -6 + x = 1.414213562 + -6 Combine like terms: 6 + -6 = 0 0 + x = 1.414213562 + -6 x = 1.414213562 + -6 Combine like terms: 1.414213562 + -6 = -4.585786438 x = -4.585786438 Simplifying x = -4.585786438Subproblem 2
x + 6 = -1.414213562 Simplifying x + 6 = -1.414213562 Reorder the terms: 6 + x = -1.414213562 Solving 6 + x = -1.414213562 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-6' to each side of the equation. 6 + -6 + x = -1.414213562 + -6 Combine like terms: 6 + -6 = 0 0 + x = -1.414213562 + -6 x = -1.414213562 + -6 Combine like terms: -1.414213562 + -6 = -7.414213562 x = -7.414213562 Simplifying x = -7.414213562Solution
The solution to the problem is based on the solutions from the subproblems. x = {-4.585786438, -7.414213562}
