Subproblem 1

Set the factor '(2 + 16x + x2)' equal to zero and attempt to solve: Simplifying 2 + 16x + x2 = 0 Solving 2 + 16x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-2' to each side of the equation. 2 + 16x + -2 + x2 = 0 + -2 Reorder the terms: 2 + -2 + 16x + x2 = 0 + -2 Combine like terms: 2 + -2 = 0 0 + 16x + x2 = 0 + -2 16x + x2 = 0 + -2 Combine like terms: 0 + -2 = -2 16x + x2 = -2 The x term is 16x. Take half its coefficient (8). Square it (64) and add it to both sides. Add '64' to each side of the equation. 16x + 64 + x2 = -2 + 64 Reorder the terms: 64 + 16x + x2 = -2 + 64 Combine like terms: -2 + 64 = 62 64 + 16x + x2 = 62 Factor a perfect square on the left side: (x + 8)(x + 8) = 62 Calculate the square root of the right side: 7.874007874 Break this problem into two subproblems by setting (x + 8) equal to 7.874007874 and -7.874007874.

Subproblem 1

x + 8 = 7.874007874 Simplifying x + 8 = 7.874007874 Reorder the terms: 8 + x = 7.874007874 Solving 8 + x = 7.874007874 Solving for variable 'x'.
