Simplifying z2 + (2 + 5i) * z + 5i = 0 Reorder the terms for easier multiplication: z2 + z(2 + 5i) + 5i = 0 z2 + (2 * z + 5i * z) + 5i = 0 Reorder the terms: z2 + (5iz + 2z) + 5i = 0 z2 + (5iz + 2z) + 5i = 0 Reorder the terms: 5i + 5iz + 2z + z2 = 0 Solving 5i + 5iz + 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. 5i + 5iz + 2z + -2z + z2 = 0 + -2z Combine like terms: 2z + -2z = 0 5i + 5iz + 0 + z2 = 0 + -2z 5i + 5iz + z2 = 0 + -2z Remove the zero: 5i + 5iz + z2 = -2z Add '-1z2' to each side of the equation. 5i + 5iz + z2 + -1z2 = -2z + -1z2 Combine like terms: z2 + -1z2 = 0 5i + 5iz + 0 = -2z + -1z2 5i + 5iz = -2z + -1z2 Reorder the terms: 5i + 5iz + 2z + z2 = -2z + 2z + -1z2 + z2 Combine like terms: -2z + 2z = 0 5i + 5iz + 2z + z2 = 0 + -1z2 + z2 5i + 5iz + 2z + z2 = -1z2 + z2 Combine like terms: -1z2 + z2 = 0 5i + 5iz + 2z + z2 = 0 The solution to this equation could not be determined.
