Q. Simplify the expression to a + bi form:(−12+2i)(−3+i)Answer:
Distribute Terms: Distribute each term in the first complex number by each term in the second complex number.(−12+2i)(−3+i)=(−12×−3)+(−12×i)+(2i×−3)+(2i×i)
Perform Multiplication: Perform the multiplication for each term.(−12×−3)=36(−12×i)=−12i(2i×−3)=−6i(2i×i)=2i2
Apply i2 Rule: Remember that i2=−1, and apply this to simplify the term with i2.2i2=2(−1)=−2
Combine Like Terms: Combine like terms. 36+(−12i)+(−6i)+(−2)=36−2−12i−6i=34−18i
Final Answer: Write the final answer in a+bi form.The simplified expression is 34−18i.
