Full solution

Q. (−90−27i)−(66+34i)= (-90-27 i)-(66+34 i)= \newlineExpress your answer in the form (a+bi) (a+b i) .
  1. Subtract Real and Imaginary Parts: To subtract complex numbers, subtract the real parts and the imaginary parts separately.\newline(−90−27i)−(66+34i)=(−90−66)−(27i+34i)(-90 - 27i) - (66 + 34i) = (-90 - 66) - (27i + 34i)
  2. Calculate Real Part: Calculate the subtraction of the real parts. −90−66=−156-90 - 66 = -156
  3. Calculate Imaginary Part: Calculate the subtraction of the imaginary parts.\newline−27i−34i=−61i-27i - 34i = -61i
  4. Combine Results: Combine the results of the real part and the imaginary part to express the answer in the form (a+bi)(a+bi). The final answer is −156−61i-156 - 61i.
