Subproblem 1

Set the factor '(5 + -11x + 8x2)' equal to zero and attempt to solve: Simplifying 5 + -11x + 8x2 = 0 Solving 5 + -11x + 8x2 = 0 Begin completing the square. Divide all terms by 8 the coefficient of the squared term: Divide each side by '8'. 0.625 + -1.375x + x2 = 0 Move the constant term to the right: Add '-0.625' to each side of the equation. 0.625 + -1.375x + -0.625 + x2 = 0 + -0.625 Reorder the terms: 0.625 + -0.625 + -1.375x + x2 = 0 + -0.625 Combine like terms: 0.625 + -0.625 = 0.000 0.000 + -1.375x + x2 = 0 + -0.625 -1.375x + x2 = 0 + -0.625 Combine like terms: 0 + -0.625 = -0.625 -1.375x + x2 = -0.625 The x term is -1.375x. Take half its coefficient (-0.6875). Square it (0.47265625) and add it to both sides. Add '0.47265625' to each side of the equation. -1.375x + 0.47265625 + x2 = -0.625 + 0.47265625 Reorder the terms: 0.47265625 + -1.375x + x2 = -0.625 + 0.47265625 Combine like terms: -0.625 + 0.47265625 = -0.15234375 0.47265625 + -1.375x + x2 = -0.15234375 Factor a perfect square on the left side: (x + -0.6875)(x + -0.6875) = -0.15234375 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.
