Simplifying (x + 1)(x + -4) = x + 7 Reorder the terms: (1 + x)(x + -4) = x + 7 Reorder the terms: (1 + x)(-4 + x) = x + 7 Multiply (1 + x) * (-4 + x) (1(-4 + x) + x(-4 + x)) = x + 7 ((-4 * 1 + x * 1) + x(-4 + x)) = x + 7 ((-4 + 1x) + x(-4 + x)) = x + 7 (-4 + 1x + (-4 * x + x * x)) = x + 7 (-4 + 1x + (-4x + x2)) = x + 7 Combine like terms: 1x + -4x = -3x (-4 + -3x + x2) = x + 7 Reorder the terms: -4 + -3x + x2 = 7 + x Solving -4 + -3x + x2 = 7 + x Solving for variable 'x'. Reorder the terms: -4 + -7 + -3x + -1x + x2 = 7 + x + -7 + -1x Combine like terms: -4 + -7 = -11 -11 + -3x + -1x + x2 = 7 + x + -7 + -1x Combine like terms: -3x + -1x = -4x -11 + -4x + x2 = 7 + x + -7 + -1x Reorder the terms: -11 + -4x + x2 = 7 + -7 + x + -1x Combine like terms: 7 + -7 = 0 -11 + -4x + x2 = 0 + x + -1x -11 + -4x + x2 = x + -1x Combine like terms: x + -1x = 0 -11 + -4x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '11' to each side of the equation. -11 + -4x + 11 + x2 = 0 + 11 Reorder the terms: -11 + 11 + -4x + x2 = 0 + 11 Combine like terms: -11 + 11 = 0 0 + -4x + x2 = 0 + 11 -4x + x2 = 0 + 11 Combine like terms: 0 + 11 = 11 -4x + x2 = 11 The x term is -4x. Take half its coefficient (-2). Square it (4) and add it to both sides. Add '4' to each side of the equation. -4x + 4 + x2 = 11 + 4 Reorder the terms: 4 + -4x + x2 = 11 + 4 Combine like terms: 11 + 4 = 15 4 + -4x + x2 = 15 Factor a perfect square on the left side: (x + -2)(x + -2) = 15 Calculate the square root of the right side: 3.872983346 Break this problem into two subproblems by setting (x + -2) equal to 3.872983346 and -3.872983346.Subproblem 1
x + -2 = 3.872983346 Simplifying x + -2 = 3.872983346 Reorder the terms: -2 + x = 3.872983346 Solving -2 + x = 3.872983346 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '2' to each side of the equation. -2 + 2 + x = 3.872983346 + 2 Combine like terms: -2 + 2 = 0 0 + x = 3.872983346 + 2 x = 3.872983346 + 2 Combine like terms: 3.872983346 + 2 = 5.872983346 x = 5.872983346 Simplifying x = 5.872983346Subproblem 2
x + -2 = -3.872983346 Simplifying x + -2 = -3.872983346 Reorder the terms: -2 + x = -3.872983346 Solving -2 + x = -3.872983346 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '2' to each side of the equation. -2 + 2 + x = -3.872983346 + 2 Combine like terms: -2 + 2 = 0 0 + x = -3.872983346 + 2 x = -3.872983346 + 2 Combine like terms: -3.872983346 + 2 = -1.872983346 x = -1.872983346 Simplifying x = -1.872983346Solution
The solution to the problem is based on the solutions from the subproblems. x = {5.872983346, -1.872983346}
