Subproblem 1

Set the factor '(-1 + 2x + -5x2)' equal to zero and attempt to solve: Simplifying -1 + 2x + -5x2 = 0 Solving -1 + 2x + -5x2 = 0 Begin completing the square. Divide all terms by -5 the coefficient of the squared term: Divide each side by '-5'. 0.2 + -0.4x + x2 = 0 Move the constant term to the right: Add '-0.2' to each side of the equation. 0.2 + -0.4x + -0.2 + x2 = 0 + -0.2 Reorder the terms: 0.2 + -0.2 + -0.4x + x2 = 0 + -0.2 Combine like terms: 0.2 + -0.2 = 0.0 0.0 + -0.4x + x2 = 0 + -0.2 -0.4x + x2 = 0 + -0.2 Combine like terms: 0 + -0.2 = -0.2 -0.4x + x2 = -0.2 The x term is -0.4x. Take half its coefficient (-0.2). Square it (0.04) and add it to both sides. Add '0.04' to each side of the equation. -0.4x + 0.04 + x2 = -0.2 + 0.04 Reorder the terms: 0.04 + -0.4x + x2 = -0.2 + 0.04 Combine like terms: -0.2 + 0.04 = -0.16 0.04 + -0.4x + x2 = -0.16 Factor a perfect square on the left side: (x + -0.2)(x + -0.2) = -0.16 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.
