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 '(10 + 8x + x2)' equal to zero and attempt to solve: Simplifying 10 + 8x + x2 = 0 Solving 10 + 8x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-10' to each side of the equation. 10 + 8x + -10 + x2 = 0 + -10 Reorder the terms: 10 + -10 + 8x + x2 = 0 + -10 Combine like terms: 10 + -10 = 0 0 + 8x + x2 = 0 + -10 8x + x2 = 0 + -10 Combine like terms: 0 + -10 = -10 8x + x2 = -10 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 = -10 + 16 Reorder the terms: 16 + 8x + x2 = -10 + 16 Combine like terms: -10 + 16 = 6 16 + 8x + x2 = 6 Factor a perfect square on the left side: (x + 4)(x + 4) = 6 Calculate the square root of the right side: 2.449489743 Break this problem into two subproblems by setting (x + 4) equal to 2.449489743 and -2.449489743.

Subproblem 1

x + 4 = 2.449489743 Simplifying x + 4 = 2.449489743 Reorder the terms: 4 + x = 2.449489743 Solving 4 + x = 2.449489743 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 = 2.449489743 + -4 Combine like terms: 4 + -4 = 0 0 + x = 2.449489743 + -4 x = 2.449489743 + -4 Combine like terms: 2.449489743 + -4 = -1.550510257 x = -1.550510257 Simplifying x = -1.550510257

Subproblem 2

x + 4 = -2.449489743 Simplifying x + 4 = -2.449489743 Reorder the terms: 4 + x = -2.449489743 Solving 4 + x = -2.449489743 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 = -2.449489743 + -4 Combine like terms: 4 + -4 = 0 0 + x = -2.449489743 + -4 x = -2.449489743 + -4 Combine like terms: -2.449489743 + -4 = -6.449489743 x = -6.449489743 Simplifying x = -6.449489743
