Subproblem 1

Set the factor '(30 + -5x + 8x2)' equal to zero and attempt to solve: Simplifying 30 + -5x + 8x2 = 0 Solving 30 + -5x + 8x2 = 0 Begin completing the square. Divide all terms by 8 the coefficient of the squared term: Divide each side by '8'. 3.75 + -0.625x + x2 = 0 Move the constant term to the right: Add '-3.75' to each side of the equation. 3.75 + -0.625x + -3.75 + x2 = 0 + -3.75 Reorder the terms: 3.75 + -3.75 + -0.625x + x2 = 0 + -3.75 Combine like terms: 3.75 + -3.75 = 0.00 0.00 + -0.625x + x2 = 0 + -3.75 -0.625x + x2 = 0 + -3.75 Combine like terms: 0 + -3.75 = -3.75 -0.625x + x2 = -3.75 The x term is -0.625x. Take half its coefficient (-0.3125). Square it (0.09765625) and add it to both sides. Add '0.09765625' to each side of the equation. -0.625x + 0.09765625 + x2 = -3.75 + 0.09765625 Reorder the terms: 0.09765625 + -0.625x + x2 = -3.75 + 0.09765625 Combine like terms: -3.75 + 0.09765625 = -3.65234375 0.09765625 + -0.625x + x2 = -3.65234375 Factor a perfect square on the left side: (x + -0.3125)(x + -0.3125) = -3.65234375 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.
