Subproblem 1

Set the factor '(4 + -1x2 + x4)' equal to zero and attempt to solve: Simplifying 4 + -1x2 + x4 = 0 Solving 4 + -1x2 + x4 = 0 Begin completing the square. Move the constant term to the right: Add '-4' to each side of the equation. 4 + -1x2 + -4 + x4 = 0 + -4 Reorder the terms: 4 + -4 + -1x2 + x4 = 0 + -4 Combine like terms: 4 + -4 = 0 0 + -1x2 + x4 = 0 + -4 -1x2 + x4 = 0 + -4 Combine like terms: 0 + -4 = -4 -1x2 + x4 = -4 The x term is -1x2. 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. -1x2 + 0.25 + x4 = -4 + 0.25 Reorder the terms: 0.25 + -1x2 + x4 = -4 + 0.25 Combine like terms: -4 + 0.25 = -3.75 0.25 + -1x2 + x4 = -3.75 Factor a perfect square on the left side: (x2 + -0.5)(x2 + -0.5) = -3.75 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.
