Subproblem 1

Set the factor '(-20 + 2x + -1x2)' equal to zero and attempt to solve: Simplifying -20 + 2x + -1x2 = 0 Solving -20 + 2x + -1x2 = 0 Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. 20 + -2x + x2 = 0 Move the constant term to the right: Add '-20' to each side of the equation. 20 + -2x + -20 + x2 = 0 + -20 Reorder the terms: 20 + -20 + -2x + x2 = 0 + -20 Combine like terms: 20 + -20 = 0 0 + -2x + x2 = 0 + -20 -2x + x2 = 0 + -20 Combine like terms: 0 + -20 = -20 -2x + x2 = -20 The x term is -2x. Take half its coefficient (-1). Square it (1) and add it to both sides. Add '1' to each side of the equation. -2x + 1 + x2 = -20 + 1 Reorder the terms: 1 + -2x + x2 = -20 + 1 Combine like terms: -20 + 1 = -19 1 + -2x + x2 = -19 Factor a perfect square on the left side: (x + -1)(x + -1) = -19 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.
