Simplifying (x + 2)(x + 2) = x * 2 + 6 Reorder the terms: (2 + x)(x + 2) = x * 2 + 6 Reorder the terms: (2 + x)(2 + x) = x * 2 + 6 Multiply (2 + x) * (2 + x) (2(2 + x) + x(2 + x)) = x * 2 + 6 ((2 * 2 + x * 2) + x(2 + x)) = x * 2 + 6 ((4 + 2x) + x(2 + x)) = x * 2 + 6 (4 + 2x + (2 * x + x * x)) = x * 2 + 6 (4 + 2x + (2x + x2)) = x * 2 + 6 Combine like terms: 2x + 2x = 4x (4 + 4x + x2) = x * 2 + 6 Reorder the terms for easier multiplication: 4 + 4x + x2 = 2x + 6 Reorder the terms: 4 + 4x + x2 = 6 + 2x Solving 4 + 4x + x2 = 6 + 2x Solving for variable 'x'. Reorder the terms: 4 + -6 + 4x + -2x + x2 = 6 + 2x + -6 + -2x Combine like terms: 4 + -6 = -2 -2 + 4x + -2x + x2 = 6 + 2x + -6 + -2x Combine like terms: 4x + -2x = 2x -2 + 2x + x2 = 6 + 2x + -6 + -2x Reorder the terms: -2 + 2x + x2 = 6 + -6 + 2x + -2x Combine like terms: 6 + -6 = 0 -2 + 2x + x2 = 0 + 2x + -2x -2 + 2x + x2 = 2x + -2x Combine like terms: 2x + -2x = 0 -2 + 2x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '2' to each side of the equation. -2 + 2x + 2 + x2 = 0 + 2 Reorder the terms: -2 + 2 + 2x + x2 = 0 + 2 Combine like terms: -2 + 2 = 0 0 + 2x + x2 = 0 + 2 2x + x2 = 0 + 2 Combine like terms: 0 + 2 = 2 2x + x2 = 2 The x term is 2x. Take half its coefficient (1). Square it (1) and add it to both sides. Add '1' to each side of the equation. 2x + 1 + x2 = 2 + 1 Reorder the terms: 1 + 2x + x2 = 2 + 1 Combine like terms: 2 + 1 = 3 1 + 2x + x2 = 3 Factor a perfect square on the left side: (x + 1)(x + 1) = 3 Calculate the square root of the right side: 1.732050808 Break this problem into two subproblems by setting (x + 1) equal to 1.732050808 and -1.732050808.Subproblem 1
x + 1 = 1.732050808 Simplifying x + 1 = 1.732050808 Reorder the terms: 1 + x = 1.732050808 Solving 1 + x = 1.732050808 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + x = 1.732050808 + -1 Combine like terms: 1 + -1 = 0 0 + x = 1.732050808 + -1 x = 1.732050808 + -1 Combine like terms: 1.732050808 + -1 = 0.732050808 x = 0.732050808 Simplifying x = 0.732050808Subproblem 2
x + 1 = -1.732050808 Simplifying x + 1 = -1.732050808 Reorder the terms: 1 + x = -1.732050808 Solving 1 + x = -1.732050808 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + x = -1.732050808 + -1 Combine like terms: 1 + -1 = 0 0 + x = -1.732050808 + -1 x = -1.732050808 + -1 Combine like terms: -1.732050808 + -1 = -2.732050808 x = -2.732050808 Simplifying x = -2.732050808Solution
The solution to the problem is based on the solutions from the subproblems. x = {0.732050808, -2.732050808}
