Subproblem 1

Set the factor '(12 + x + 8x2)' equal to zero and attempt to solve: Simplifying 12 + x + 8x2 = 0 Solving 12 + x + 8x2 = 0 Begin completing the square. Divide all terms by 8 the coefficient of the squared term: Divide each side by '8'. 1.5 + 0.125x + x2 = 0 Move the constant term to the right: Add '-1.5' to each side of the equation. 1.5 + 0.125x + -1.5 + x2 = 0 + -1.5 Reorder the terms: 1.5 + -1.5 + 0.125x + x2 = 0 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + 0.125x + x2 = 0 + -1.5 0.125x + x2 = 0 + -1.5 Combine like terms: 0 + -1.5 = -1.5 0.125x + x2 = -1.5 The x term is x. Take half its coefficient (0.5). Square it (0.25) and add it to both sides. Add '0.25' to each side of the equation. 0.125x + 0.25 + x2 = -1.5 + 0.25 Reorder the terms: 0.25 + 0.125x + x2 = -1.5 + 0.25 Combine like terms: -1.5 + 0.25 = -1.25 0.25 + 0.125x + x2 = -1.25 Factor a perfect square on the left side: (x + 0.5)(x + 0.5) = -1.25 Can't calculate square root of the right side. The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined. The solution to this equation could not be determined.
