Simplifying (7 + 2I)(7 + 2i) = 0 Multiply (7 + 2I) * (7 + 2i) (7(7 + 2i) + 2I * (7 + 2i)) = 0 ((7 * 7 + 2i * 7) + 2I * (7 + 2i)) = 0 ((49 + 14i) + 2I * (7 + 2i)) = 0 (49 + 14i + (7 * 2I + 2i * 2I)) = 0 (49 + 14i + (14I + 4iI)) = 0 Reorder the terms: (49 + 14I + 14i + 4iI) = 0 (49 + 14I + 14i + 4iI) = 0 Solving 49 + 14I + 14i + 4iI = 0 Solving for variable 'I'. Move all terms containing I to the left, all other terms to the right. Add '-49' to each side of the equation. 49 + 14I + 14i + -49 + 4iI = 0 + -49 Reorder the terms: 49 + -49 + 14I + 14i + 4iI = 0 + -49 Combine like terms: 49 + -49 = 0 0 + 14I + 14i + 4iI = 0 + -49 14I + 14i + 4iI = 0 + -49 Combine like terms: 0 + -49 = -49 14I + 14i + 4iI = -49 Add '-14i' to each side of the equation. 14I + 14i + -14i + 4iI = -49 + -14i Combine like terms: 14i + -14i = 0 14I + 0 + 4iI = -49 + -14i 14I + 4iI = -49 + -14i Reorder the terms: 49 + 14I + 14i + 4iI = -49 + -14i + 49 + 14i Reorder the terms: 49 + 14I + 14i + 4iI = -49 + 49 + -14i + 14i Combine like terms: -49 + 49 = 0 49 + 14I + 14i + 4iI = 0 + -14i + 14i 49 + 14I + 14i + 4iI = -14i + 14i Combine like terms: -14i + 14i = 0 49 + 14I + 14i + 4iI = 0 The solution to this equation could not be determined.
