Subproblem 1

Set the factor '(-18 + 8x + x2)' equal to zero and attempt to solve: Simplifying -18 + 8x + x2 = 0 Solving -18 + 8x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '18' to each side of the equation. -18 + 8x + 18 + x2 = 0 + 18 Reorder the terms: -18 + 18 + 8x + x2 = 0 + 18 Combine like terms: -18 + 18 = 0 0 + 8x + x2 = 0 + 18 8x + x2 = 0 + 18 Combine like terms: 0 + 18 = 18 8x + x2 = 18 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 = 18 + 16 Reorder the terms: 16 + 8x + x2 = 18 + 16 Combine like terms: 18 + 16 = 34 16 + 8x + x2 = 34 Factor a perfect square on the left side: (x + 4)(x + 4) = 34 Calculate the square root of the right side: 5.830951895 Break this problem into two subproblems by setting (x + 4) equal to 5.830951895 and -5.830951895.

Subproblem 1

x + 4 = 5.830951895 Simplifying x + 4 = 5.830951895 Reorder the terms: 4 + x = 5.830951895 Solving 4 + x = 5.830951895 Solving for variable 'x'.
