What is the quotient of complex numbers below? QUESTION IS IN THE PICTURE PLEASE HELP
scZoUnD [109]

Answer:

B (3 - i)

Step-by-step explanation:

To find the quotient of the complex numbers you must multiply the numerator and the denominator by the conjugate of the denominator

Example: The conjugate of (3 - i) is (3 + i)

\frac{8-6i}{3-i} *\frac{3+i}{3+i}

(3-i)(3+i)=9-i^{2}

i^{2}=-1

So (3-i)(3+i)=9--1=10

Denominator= 10

(8-6i)(3+i)=24+8i-18i-6i^{2}

24-10i-6i^{2} =24-10i-6(-1)=24-10i+6=30-10i

Numerator = 30 - 10i

Then \frac{30-10i}{10} =\frac{30}{10}-\frac{10i}{10}  = 3 - i

The correct answer is B
