Subproblem 1

Set the factor '(20 + x + 2x2)' equal to zero and attempt to solve: Simplifying 20 + x + 2x2 = 0 Solving 20 + x + 2x2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. 10 + 0.5x + x2 = 0 Move the constant term to the right: Add '-10' to each side of the equation. 10 + 0.5x + -10 + x2 = 0 + -10 Reorder the terms: 10 + -10 + 0.5x + x2 = 0 + -10 Combine like terms: 10 + -10 = 0 0 + 0.5x + x2 = 0 + -10 0.5x + x2 = 0 + -10 Combine like terms: 0 + -10 = -10 0.5x + x2 = -10 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 = -10 + 0.25 Reorder the terms: 0.25 + 0.5x + x2 = -10 + 0.25 Combine like terms: -10 + 0.25 = -9.75 0.25 + 0.5x + x2 = -9.75 Factor a perfect square on the left side: (x + 0.5)(x + 0.5) = -9.75 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.
