Subproblem 1

Set the factor '(11 + 21x + 20x2)' equal to zero and attempt to solve: Simplifying 11 + 21x + 20x2 = 0 Solving 11 + 21x + 20x2 = 0 Begin completing the square. Divide all terms by 20 the coefficient of the squared term: Divide each side by '20'. 0.55 + 1.05x + x2 = 0.0 Move the constant term to the right: Add '-0.55' to each side of the equation. 0.55 + 1.05x + -0.55 + x2 = 0.0 + -0.55 Reorder the terms: 0.55 + -0.55 + 1.05x + x2 = 0.0 + -0.55 Combine like terms: 0.55 + -0.55 = 0.00 0.00 + 1.05x + x2 = 0.0 + -0.55 1.05x + x2 = 0.0 + -0.55 Combine like terms: 0.0 + -0.55 = -0.55 1.05x + x2 = -0.55 The x term is 1.05x. Take half its coefficient (0.525). Square it (0.275625) and add it to both sides. Add '0.275625' to each side of the equation. 1.05x + 0.275625 + x2 = -0.55 + 0.275625 Reorder the terms: 0.275625 + 1.05x + x2 = -0.55 + 0.275625 Combine like terms: -0.55 + 0.275625 = -0.274375 0.275625 + 1.05x + x2 = -0.274375 Factor a perfect square on the left side: (x + 0.525)(x + 0.525) = -0.274375 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.
