Simplifying x2 + 4x + Ix + -2I = 0 Reorder the terms: -2I + 4x + xI + x2 = 0 Solving -2I + 4x + xI + x2 = 0 Solving for variable 'I'. Move all terms containing I to the left, all other terms to the right. Add '-4x' to each side of the equation. -2I + 4x + xI + -4x + x2 = 0 + -4x Reorder the terms: -2I + 4x + -4x + xI + x2 = 0 + -4x Combine like terms: 4x + -4x = 0 -2I + 0 + xI + x2 = 0 + -4x -2I + xI + x2 = 0 + -4x Remove the zero: -2I + xI + x2 = -4x Add '-1x2' to each side of the equation. -2I + xI + x2 + -1x2 = -4x + -1x2 Combine like terms: x2 + -1x2 = 0 -2I + xI + 0 = -4x + -1x2 -2I + xI = -4x + -1x2 Reorder the terms: -2I + 4x + xI + x2 = -4x + -1x2 + 4x + x2 Reorder the terms: -2I + 4x + xI + x2 = -4x + 4x + -1x2 + x2 Combine like terms: -4x + 4x = 0 -2I + 4x + xI + x2 = 0 + -1x2 + x2 -2I + 4x + xI + x2 = -1x2 + x2 Combine like terms: -1x2 + x2 = 0 -2I + 4x + xI + x2 = 0 The solution to this equation could not be determined.
