Subproblem 1

Set the factor '(13 + 7x + 8x2)' equal to zero and attempt to solve: Simplifying 13 + 7x + 8x2 = 0 Solving 13 + 7x + 8x2 = 0 Begin completing the square. Divide all terms by 8 the coefficient of the squared term: Divide each side by '8'. 1.625 + 0.875x + x2 = 0 Move the constant term to the right: Add '-1.625' to each side of the equation. 1.625 + 0.875x + -1.625 + x2 = 0 + -1.625 Reorder the terms: 1.625 + -1.625 + 0.875x + x2 = 0 + -1.625 Combine like terms: 1.625 + -1.625 = 0.000 0.000 + 0.875x + x2 = 0 + -1.625 0.875x + x2 = 0 + -1.625 Combine like terms: 0 + -1.625 = -1.625 0.875x + x2 = -1.625 The x term is 0.875x. Take half its coefficient (0.4375). Square it (0.19140625) and add it to both sides. Add '0.19140625' to each side of the equation. 0.875x + 0.19140625 + x2 = -1.625 + 0.19140625 Reorder the terms: 0.19140625 + 0.875x + x2 = -1.625 + 0.19140625 Combine like terms: -1.625 + 0.19140625 = -1.43359375 0.19140625 + 0.875x + x2 = -1.43359375 Factor a perfect square on the left side: (x + 0.4375)(x + 0.4375) = -1.43359375 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.
