Solution for (18-9i)(2+I)= equation:


Simplifying
(18 + -9i)(2 + I) = 0

Multiply (18 + -9i) * (2 + I)
(18(2 + I) + -9i * (2 + I)) = 0
((2 * 18 + I * 18) + -9i * (2 + I)) = 0
((36 + 18I) + -9i * (2 + I)) = 0
(36 + 18I + (2 * -9i + I * -9i)) = 0
(36 + 18I + (-18i + -9iI)) = 0
(36 + 18I + -18i + -9iI) = 0

Solving
36 + 18I + -18i + -9iI = 0
