Subproblem 1

Set the factor '(2 + 3x + 4x2)' equal to zero and attempt to solve: Simplifying 2 + 3x + 4x2 = 0 Solving 2 + 3x + 4x2 = 0 Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. 0.5 + 0.75x + x2 = 0 Move the constant term to the right: Add '-0.5' to each side of the equation. 0.5 + 0.75x + -0.5 + x2 = 0 + -0.5 Reorder the terms: 0.5 + -0.5 + 0.75x + x2 = 0 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + 0.75x + x2 = 0 + -0.5 0.75x + x2 = 0 + -0.5 Combine like terms: 0 + -0.5 = -0.5 0.75x + x2 = -0.5 The x term is 0.75x. Take half its coefficient (0.375). Square it (0.140625) and add it to both sides. Add '0.140625' to each side of the equation. 0.75x + 0.140625 + x2 = -0.5 + 0.140625 Reorder the terms: 0.140625 + 0.75x + x2 = -0.5 + 0.140625 Combine like terms: -0.5 + 0.140625 = -0.359375 0.140625 + 0.75x + x2 = -0.359375 Factor a perfect square on the left side: (x + 0.375)(x + 0.375) = -0.359375 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.
