Simplifying (x + 7)(x + 1) = 54 Reorder the terms: (7 + x)(x + 1) = 54 Reorder the terms: (7 + x)(1 + x) = 54 Multiply (7 + x) * (1 + x) (7(1 + x) + x(1 + x)) = 54 ((1 * 7 + x * 7) + x(1 + x)) = 54 ((7 + 7x) + x(1 + x)) = 54 (7 + 7x + (1 * x + x * x)) = 54 (7 + 7x + (1x + x2)) = 54 Combine like terms: 7x + 1x = 8x (7 + 8x + x2) = 54 Solving 7 + 8x + x2 = 54 Solving for variable 'x'. Reorder the terms: 7 + -54 + 8x + x2 = 54 + -54 Combine like terms: 7 + -54 = -47 -47 + 8x + x2 = 54 + -54 Combine like terms: 54 + -54 = 0 -47 + 8x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '47' to each side of the equation. -47 + 8x + 47 + x2 = 0 + 47 Reorder the terms: -47 + 47 + 8x + x2 = 0 + 47 Combine like terms: -47 + 47 = 0 0 + 8x + x2 = 0 + 47 8x + x2 = 0 + 47 Combine like terms: 0 + 47 = 47 8x + x2 = 47 The x term is 8x. Take half its coefficient (4). Square it (16) and add it to both sides. Add '16' to each side of the equation. 8x + 16 + x2 = 47 + 16 Reorder the terms: 16 + 8x + x2 = 47 + 16 Combine like terms: 47 + 16 = 63 16 + 8x + x2 = 63 Factor a perfect square on the left side: (x + 4)(x + 4) = 63 Calculate the square root of the right side: 7.937253933 Break this problem into two subproblems by setting (x + 4) equal to 7.937253933 and -7.937253933.Subproblem 1
x + 4 = 7.937253933 Simplifying x + 4 = 7.937253933 Reorder the terms: 4 + x = 7.937253933 Solving 4 + x = 7.937253933 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-4' to each side of the equation. 4 + -4 + x = 7.937253933 + -4 Combine like terms: 4 + -4 = 0 0 + x = 7.937253933 + -4 x = 7.937253933 + -4 Combine like terms: 7.937253933 + -4 = 3.937253933 x = 3.937253933 Simplifying x = 3.937253933Subproblem 2
x + 4 = -7.937253933 Simplifying x + 4 = -7.937253933 Reorder the terms: 4 + x = -7.937253933 Solving 4 + x = -7.937253933 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-4' to each side of the equation. 4 + -4 + x = -7.937253933 + -4 Combine like terms: 4 + -4 = 0 0 + x = -7.937253933 + -4 x = -7.937253933 + -4 Combine like terms: -7.937253933 + -4 = -11.937253933 x = -11.937253933 Simplifying x = -11.937253933Solution
The solution to the problem is based on the solutions from the subproblems. x = {3.937253933, -11.937253933}
