Simplifying z2 + (2 + -1i) * z + -2i = 0 Reorder the terms for easier multiplication: z2 + z(2 + -1i) + -2i = 0 z2 + (2 * z + -1i * z) + -2i = 0 Reorder the terms: z2 + (-1iz + 2z) + -2i = 0 z2 + (-1iz + 2z) + -2i = 0 Reorder the terms: -2i + -1iz + 2z + z2 = 0 Solving -2i + -1iz + 2z + z2 = 0 Solving for variable 'i'. Move all terms containing i to the left, all other terms to the right. Add '-2z' to each side of the equation. -2i + -1iz + 2z + -2z + z2 = 0 + -2z Combine like terms: 2z + -2z = 0 -2i + -1iz + 0 + z2 = 0 + -2z -2i + -1iz + z2 = 0 + -2z Remove the zero: -2i + -1iz + z2 = -2z Add '-1z2' to each side of the equation. -2i + -1iz + z2 + -1z2 = -2z + -1z2 Combine like terms: z2 + -1z2 = 0 -2i + -1iz + 0 = -2z + -1z2 -2i + -1iz = -2z + -1z2 Reorder the terms: -2i + -1iz + 2z + z2 = -2z + 2z + -1z2 + z2 Combine like terms: -2z + 2z = 0 -2i + -1iz + 2z + z2 = 0 + -1z2 + z2 -2i + -1iz + 2z + z2 = -1z2 + z2 Combine like terms: -1z2 + z2 = 0 -2i + -1iz + 2z + z2 = 0 The solution to this equation could not be determined.
