Simplifying x + (x + 2)(x + 4) = 392 Reorder the terms: x + (2 + x)(x + 4) = 392 Reorder the terms: x + (2 + x)(4 + x) = 392 Multiply (2 + x) * (4 + x) x + (2(4 + x) + x(4 + x)) = 392 x + ((4 * 2 + x * 2) + x(4 + x)) = 392 x + ((8 + 2x) + x(4 + x)) = 392 x + (8 + 2x + (4 * x + x * x)) = 392 x + (8 + 2x + (4x + x2)) = 392 Combine like terms: 2x + 4x = 6x x + (8 + 6x + x2) = 392 Reorder the terms: 8 + x + 6x + x2 = 392 Combine like terms: x + 6x = 7x 8 + 7x + x2 = 392 Solving 8 + 7x + x2 = 392 Solving for variable 'x'. Reorder the terms: 8 + -392 + 7x + x2 = 392 + -392 Combine like terms: 8 + -392 = -384 -384 + 7x + x2 = 392 + -392 Combine like terms: 392 + -392 = 0 -384 + 7x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '384' to each side of the equation. -384 + 7x + 384 + x2 = 0 + 384 Reorder the terms: -384 + 384 + 7x + x2 = 0 + 384 Combine like terms: -384 + 384 = 0 0 + 7x + x2 = 0 + 384 7x + x2 = 0 + 384 Combine like terms: 0 + 384 = 384 7x + x2 = 384 The x term is 7x. Take half its coefficient (3.5). Square it (12.25) and add it to both sides. Add '12.25' to each side of the equation. 7x + 12.25 + x2 = 384 + 12.25 Reorder the terms: 12.25 + 7x + x2 = 384 + 12.25 Combine like terms: 384 + 12.25 = 396.25 12.25 + 7x + x2 = 396.25 Factor a perfect square on the left side: (x + 3.5)(x + 3.5) = 396.25 Calculate the square root of the right side: 19.906029237 Break this problem into two subproblems by setting (x + 3.5) equal to 19.906029237 and -19.906029237.Subproblem 1
x + 3.5 = 19.906029237 Simplifying x + 3.5 = 19.906029237 Reorder the terms: 3.5 + x = 19.906029237 Solving 3.5 + x = 19.906029237 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-3.5' to each side of the equation. 3.5 + -3.5 + x = 19.906029237 + -3.5 Combine like terms: 3.5 + -3.5 = 0.0 0.0 + x = 19.906029237 + -3.5 x = 19.906029237 + -3.5 Combine like terms: 19.906029237 + -3.5 = 16.406029237 x = 16.406029237 Simplifying x = 16.406029237Subproblem 2
x + 3.5 = -19.906029237 Simplifying x + 3.5 = -19.906029237 Reorder the terms: 3.5 + x = -19.906029237 Solving 3.5 + x = -19.906029237 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-3.5' to each side of the equation. 3.5 + -3.5 + x = -19.906029237 + -3.5 Combine like terms: 3.5 + -3.5 = 0.0 0.0 + x = -19.906029237 + -3.5 x = -19.906029237 + -3.5 Combine like terms: -19.906029237 + -3.5 = -23.406029237 x = -23.406029237 Simplifying x = -23.406029237Solution
The solution to the problem is based on the solutions from the subproblems. x = {16.406029237, -23.406029237}
