Subproblem 1

Set the factor 'x' equal to zero and attempt to solve: Simplifying x = 0 Solving x = 0 Move all terms containing x to the left, all other terms to the right. Simplifying x = 0

Subproblem 2

Set the factor '(5 + 8x + x2)' equal to zero and attempt to solve: Simplifying 5 + 8x + x2 = 0 Solving 5 + 8x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-5' to each side of the equation. 5 + 8x + -5 + x2 = 0 + -5 Reorder the terms: 5 + -5 + 8x + x2 = 0 + -5 Combine like terms: 5 + -5 = 0 0 + 8x + x2 = 0 + -5 8x + x2 = 0 + -5 Combine like terms: 0 + -5 = -5 8x + x2 = -5 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 = -5 + 16 Reorder the terms: 16 + 8x + x2 = -5 + 16 Combine like terms: -5 + 16 = 11 16 + 8x + x2 = 11 Factor a perfect square on the left side: (x + 4)(x + 4) = 11 Calculate the square root of the right side: 3.31662479 Break this problem into two subproblems by setting (x + 4) equal to 3.31662479 and -3.31662479.

Subproblem 1

x + 4 = 3.31662479 Simplifying x + 4 = 3.31662479 Reorder the terms: 4 + x = 3.31662479 Solving 4 + x = 3.31662479 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 = 3.31662479 + -4 Combine like terms: 4 + -4 = 0 0 + x = 3.31662479 + -4 x = 3.31662479 + -4 Combine like terms: 3.31662479 + -4 = -0.68337521 x = -0.68337521 Simplifying x = -0.68337521

Subproblem 2
