Subproblem 1

Set the factor '(1 + x + 2x2)' equal to zero and attempt to solve: Simplifying 1 + x + 2x2 = 0 Solving 1 + x + 2x2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. 0.5 + 0.5x + x2 = 0 Move the constant term to the right: Add '-0.5' to each side of the equation. 0.5 + 0.5x + -0.5 + x2 = 0 + -0.5 Reorder the terms: 0.5 + -0.5 + 0.5x + x2 = 0 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + 0.5x + x2 = 0 + -0.5 0.5x + x2 = 0 + -0.5 Combine like terms: 0 + -0.5 = -0.5 0.5x + x2 = -0.5 The x term is x. Take half its coefficient (0.5). Square it (0.25) and add it to both sides. Add '0.25' to each side of the equation. 0.5x + 0.25 + x2 = -0.5 + 0.25 Reorder the terms: 0.25 + 0.5x + x2 = -0.5 + 0.25 Combine like terms: -0.5 + 0.25 = -0.25 0.25 + 0.5x + x2 = -0.25 Factor a perfect square on the left side: (x + 0.5)(x + 0.5) = -0.25 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.
