Simplifying (x + 4)(x + 4) = 8 Reorder the terms: (4 + x)(x + 4) = 8 Reorder the terms: (4 + x)(4 + x) = 8 Multiply (4 + x) * (4 + x) (4(4 + x) + x(4 + x)) = 8 ((4 * 4 + x * 4) + x(4 + x)) = 8 ((16 + 4x) + x(4 + x)) = 8 (16 + 4x + (4 * x + x * x)) = 8 (16 + 4x + (4x + x2)) = 8 Combine like terms: 4x + 4x = 8x (16 + 8x + x2) = 8 Solving 16 + 8x + x2 = 8 Solving for variable 'x'. Reorder the terms: 16 + -8 + 8x + x2 = 8 + -8 Combine like terms: 16 + -8 = 8 8 + 8x + x2 = 8 + -8 Combine like terms: 8 + -8 = 0 8 + 8x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-8' to each side of the equation. 8 + 8x + -8 + x2 = 0 + -8 Reorder the terms: 8 + -8 + 8x + x2 = 0 + -8 Combine like terms: 8 + -8 = 0 0 + 8x + x2 = 0 + -8 8x + x2 = 0 + -8 Combine like terms: 0 + -8 = -8 8x + x2 = -8 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 = -8 + 16 Reorder the terms: 16 + 8x + x2 = -8 + 16 Combine like terms: -8 + 16 = 8 16 + 8x + x2 = 8 Factor a perfect square on the left side: (x + 4)(x + 4) = 8 Calculate the square root of the right side: 2.828427125 Break this problem into two subproblems by setting (x + 4) equal to 2.828427125 and -2.828427125.Subproblem 1
x + 4 = 2.828427125 Simplifying x + 4 = 2.828427125 Reorder the terms: 4 + x = 2.828427125 Solving 4 + x = 2.828427125 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 = 2.828427125 + -4 Combine like terms: 4 + -4 = 0 0 + x = 2.828427125 + -4 x = 2.828427125 + -4 Combine like terms: 2.828427125 + -4 = -1.171572875 x = -1.171572875 Simplifying x = -1.171572875Subproblem 2
x + 4 = -2.828427125 Simplifying x + 4 = -2.828427125 Reorder the terms: 4 + x = -2.828427125 Solving 4 + x = -2.828427125 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 = -2.828427125 + -4 Combine like terms: 4 + -4 = 0 0 + x = -2.828427125 + -4 x = -2.828427125 + -4 Combine like terms: -2.828427125 + -4 = -6.828427125 x = -6.828427125 Simplifying x = -6.828427125Solution
The solution to the problem is based on the solutions from the subproblems. x = {-1.171572875, -6.828427125}
