Subproblem 1

Set the factor '(41 + 6x + 4x2)' equal to zero and attempt to solve: Simplifying 41 + 6x + 4x2 = 0 Solving 41 + 6x + 4x2 = 0 Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. 10.25 + 1.5x + x2 = 0 Move the constant term to the right: Add '-10.25' to each side of the equation. 10.25 + 1.5x + -10.25 + x2 = 0 + -10.25 Reorder the terms: 10.25 + -10.25 + 1.5x + x2 = 0 + -10.25 Combine like terms: 10.25 + -10.25 = 0.00 0.00 + 1.5x + x2 = 0 + -10.25 1.5x + x2 = 0 + -10.25 Combine like terms: 0 + -10.25 = -10.25 1.5x + x2 = -10.25 The x term is 1.5x. Take half its coefficient (0.75). Square it (0.5625) and add it to both sides. Add '0.5625' to each side of the equation. 1.5x + 0.5625 + x2 = -10.25 + 0.5625 Reorder the terms: 0.5625 + 1.5x + x2 = -10.25 + 0.5625 Combine like terms: -10.25 + 0.5625 = -9.6875 0.5625 + 1.5x + x2 = -9.6875 Factor a perfect square on the left side: (x + 0.75)(x + 0.75) = -9.6875 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.
