Subproblem 2

Set the factor '(1 + X2 + X4)' equal to zero and attempt to solve: Simplifying 1 + X2 + X4 = 0 Solving 1 + X2 + X4 = 0 Begin completing the square. Move the constant term to the right: Add '-1' to each side of the equation. 1 + X2 + -1 + X4 = 0 + -1 Reorder the terms: 1 + -1 + X2 + X4 = 0 + -1 Combine like terms: 1 + -1 = 0 0 + X2 + X4 = 0 + -1 X2 + X4 = 0 + -1 Combine like terms: 0 + -1 = -1 X2 + X4 = -1 The X term is X2. 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. X2 + 0.25 + X4 = -1 + 0.25 Reorder the terms: 0.25 + X2 + X4 = -1 + 0.25 Combine like terms: -1 + 0.25 = -0.75 0.25 + X2 + X4 = -0.75 Factor a perfect square on the left side: (X2 + 0.5)(X2 + 0.5) = -0.75 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.
