Question

3+4i/4-5i fast solution ​

Answer 1

Answer:

x = -8/31 , y = 1

Step-by-step explanation:

3+ 4i/4-5i x 4+5i/4+5i................... divide and multiply with its conjugate.

hence we get,

(3+4i)(4+5i) / (4-5i)(4+5i)

12 + 15i + 16i -20 / 16 + 25

-8 + 31i / 31

-8/31 + 31/31i

-8/31 + 1i

hence x = -8/31 , y = 1
