It is only when multiplying and dividing complex numbers that there is the special step where is transformed into. Multiplying the complex numbers and also making a mistake when multiplying may lead to the wrong answer choice. Incorrectly multiplying the complex numbers rather than subtracting them will lead to the wrong answer choice. Students who are expecting the question to be more challenging than it actually is may see the complex numbers in parentheses and jump to the conclusion that they need to multiply the complex numbers rather than just subtract them. ![]() Failure to do this step correctly can lead to the wrong answer choice.
