Simplifying (x + 1)(x + -7) = 1 Reorder the terms: (1 + x)(x + -7) = 1 Reorder the terms: (1 + x)(-7 + x) = 1 Multiply (1 + x) * (-7 + x) (1(-7 + x) + x(-7 + x)) = 1 ((-7 * 1 + x * 1) + x(-7 + x)) = 1 ((-7 + 1x) + x(-7 + x)) = 1 (-7 + 1x + (-7 * x + x * x)) = 1 (-7 + 1x + (-7x + x2)) = 1 Combine like terms: 1x + -7x = -6x (-7 + -6x + x2) = 1 Solving -7 + -6x + x2 = 1 Solving for variable 'x'. Reorder the terms: -7 + -1 + -6x + x2 = 1 + -1 Combine like terms: -7 + -1 = -8 -8 + -6x + x2 = 1 + -1 Combine like terms: 1 + -1 = 0 -8 + -6x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '8' to each side of the equation. -8 + -6x + 8 + x2 = 0 + 8 Reorder the terms: -8 + 8 + -6x + x2 = 0 + 8 Combine like terms: -8 + 8 = 0 0 + -6x + x2 = 0 + 8 -6x + x2 = 0 + 8 Combine like terms: 0 + 8 = 8 -6x + x2 = 8 The x term is -6x. Take half its coefficient (-3). Square it (9) and add it to both sides. Add '9' to each side of the equation. -6x + 9 + x2 = 8 + 9 Reorder the terms: 9 + -6x + x2 = 8 + 9 Combine like terms: 8 + 9 = 17 9 + -6x + x2 = 17 Factor a perfect square on the left side: (x + -3)(x + -3) = 17 Calculate the square root of the right side: 4.123105626 Break this problem into two subproblems by setting (x + -3) equal to 4.123105626 and -4.123105626.Subproblem 1
x + -3 = 4.123105626 Simplifying x + -3 = 4.123105626 Reorder the terms: -3 + x = 4.123105626 Solving -3 + x = 4.123105626 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '3' to each side of the equation. -3 + 3 + x = 4.123105626 + 3 Combine like terms: -3 + 3 = 0 0 + x = 4.123105626 + 3 x = 4.123105626 + 3 Combine like terms: 4.123105626 + 3 = 7.123105626 x = 7.123105626 Simplifying x = 7.123105626Subproblem 2
x + -3 = -4.123105626 Simplifying x + -3 = -4.123105626 Reorder the terms: -3 + x = -4.123105626 Solving -3 + x = -4.123105626 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '3' to each side of the equation. -3 + 3 + x = -4.123105626 + 3 Combine like terms: -3 + 3 = 0 0 + x = -4.123105626 + 3 x = -4.123105626 + 3 Combine like terms: -4.123105626 + 3 = -1.123105626 x = -1.123105626 Simplifying x = -1.123105626Solution
The solution to the problem is based on the solutions from the subproblems. x = {7.123105626, -1.123105626}
