Q. Divide the following complex numbers.−4−i11+24i
Problem Statement: Write down the problem to solve.Divide the complex numbers (11+24i) by (−4−i).
Multiply by Conjugate: Multiply the numerator and the denominator by the conjugate of the denominator. The conjugate of (−4−i) is (−4+i). We multiply both the numerator and the denominator by this conjugate to remove the imaginary part from the denominator. (−4−i)(−4+i)(11+24i)(−4+i)
Expand Numerator: Expand the numerator using the distributive property (FOIL method).(11+24i)(−4+i)=11(−4)+11(i)+24i(−4)+24i(i)=−44−11i−96i−24i2Since i2=−1, we have:=−44−11i−96i+24=−20−107i
Expand Denominator: Expand the denominator using the distributive property.(−4−i)(−4+i)=(−4)(−4)+(−4)(i)−i(−4)−i(i)=16−4i+4i−i2Since i2=−1, we have:=16+1=17
Write Division: Write the division of the expanded numerator by the expanded denominator.17−20−107i
Divide Numerator by Denominator: Divide each term in the numerator by the denominator separately.−1720−17107i
Simplify Division: Simplify the division for each term. −1720−17107i
