Subproblem 1

Set the factor '(4 + 3x + 4x2)' equal to zero and attempt to solve: Simplifying 4 + 3x + 4x2 = 0 Solving 4 + 3x + 4x2 = 0 Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. 1 + 0.75x + x2 = 0 Move the constant term to the right: Add '-1' to each side of the equation. 1 + 0.75x + -1 + x2 = 0 + -1 Reorder the terms: 1 + -1 + 0.75x + x2 = 0 + -1 Combine like terms: 1 + -1 = 0 0 + 0.75x + x2 = 0 + -1 0.75x + x2 = 0 + -1 Combine like terms: 0 + -1 = -1 0.75x + x2 = -1 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 = -1 + 0.140625 Reorder the terms: 0.140625 + 0.75x + x2 = -1 + 0.140625 Combine like terms: -1 + 0.140625 = -0.859375 0.140625 + 0.75x + x2 = -0.859375 Factor a perfect square on the left side: (x + 0.375)(x + 0.375) = -0.859375 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.
