Simplifying (x + 7)(x + 5) = 16 Reorder the terms: (7 + x)(x + 5) = 16 Reorder the terms: (7 + x)(5 + x) = 16 Multiply (7 + x) * (5 + x) (7(5 + x) + x(5 + x)) = 16 ((5 * 7 + x * 7) + x(5 + x)) = 16 ((35 + 7x) + x(5 + x)) = 16 (35 + 7x + (5 * x + x * x)) = 16 (35 + 7x + (5x + x2)) = 16 Combine like terms: 7x + 5x = 12x (35 + 12x + x2) = 16 Solving 35 + 12x + x2 = 16 Solving for variable 'x'. Reorder the terms: 35 + -16 + 12x + x2 = 16 + -16 Combine like terms: 35 + -16 = 19 19 + 12x + x2 = 16 + -16 Combine like terms: 16 + -16 = 0 19 + 12x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-19' to each side of the equation. 19 + 12x + -19 + x2 = 0 + -19 Reorder the terms: 19 + -19 + 12x + x2 = 0 + -19 Combine like terms: 19 + -19 = 0 0 + 12x + x2 = 0 + -19 12x + x2 = 0 + -19 Combine like terms: 0 + -19 = -19 12x + x2 = -19 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 = -19 + 36 Reorder the terms: 36 + 12x + x2 = -19 + 36 Combine like terms: -19 + 36 = 17 36 + 12x + x2 = 17 Factor a perfect square on the left side: (x + 6)(x + 6) = 17 Calculate the square root of the right side: 4.123105626 Break this problem into two subproblems by setting (x + 6) equal to 4.123105626 and -4.123105626.Subproblem 1
x + 6 = 4.123105626 Simplifying x + 6 = 4.123105626 Reorder the terms: 6 + x = 4.123105626 Solving 6 + x = 4.123105626 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 = 4.123105626 + -6 Combine like terms: 6 + -6 = 0 0 + x = 4.123105626 + -6 x = 4.123105626 + -6 Combine like terms: 4.123105626 + -6 = -1.876894374 x = -1.876894374 Simplifying x = -1.876894374Subproblem 2
x + 6 = -4.123105626 Simplifying x + 6 = -4.123105626 Reorder the terms: 6 + x = -4.123105626 Solving 6 + x = -4.123105626 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 = -4.123105626 + -6 Combine like terms: 6 + -6 = 0 0 + x = -4.123105626 + -6 x = -4.123105626 + -6 Combine like terms: -4.123105626 + -6 = -10.123105626 x = -10.123105626 Simplifying x = -10.123105626Solution
The solution to the problem is based on the solutions from the subproblems. x = {-1.876894374, -10.123105626}
