Simplifying (4 + I)(7 + -9i) = 0 Multiply (4 + I) * (7 + -9i) (4(7 + -9i) + I(7 + -9i)) = 0 ((7 * 4 + -9i * 4) + I(7 + -9i)) = 0 ((28 + -36i) + I(7 + -9i)) = 0 (28 + -36i + (7 * I + -9i * I)) = 0 (28 + -36i + (7I + -9iI)) = 0 Reorder the terms: (28 + 7I + -36i + -9iI) = 0 (28 + 7I + -36i + -9iI) = 0 Solving 28 + 7I + -36i + -9iI = 0 Solving for variable 'I'. Move all terms containing I to the left, all other terms to the right. Add '-28' to each side of the equation. 28 + 7I + -36i + -28 + -9iI = 0 + -28 Reorder the terms: 28 + -28 + 7I + -36i + -9iI = 0 + -28 Combine like terms: 28 + -28 = 0 0 + 7I + -36i + -9iI = 0 + -28 7I + -36i + -9iI = 0 + -28 Combine like terms: 0 + -28 = -28 7I + -36i + -9iI = -28 Add '36i' to each side of the equation. 7I + -36i + 36i + -9iI = -28 + 36i Combine like terms: -36i + 36i = 0 7I + 0 + -9iI = -28 + 36i 7I + -9iI = -28 + 36i Reorder the terms: 28 + 7I + -36i + -9iI = -28 + 36i + 28 + -36i Reorder the terms: 28 + 7I + -36i + -9iI = -28 + 28 + 36i + -36i Combine like terms: -28 + 28 = 0 28 + 7I + -36i + -9iI = 0 + 36i + -36i 28 + 7I + -36i + -9iI = 36i + -36i Combine like terms: 36i + -36i = 0 28 + 7I + -36i + -9iI = 0 The solution to this equation could not be determined.
