Question

find the values of x and y if...........
(use i²=-1)​

Answer 1

Step-by-step explanation:

[(x+1)(1-i)+(y-1)(1+i)]/1-i^2

(x+y+iy-ix-2i)/2=i

x+y+iy-ix=4i

squaring on both side.

x^2+y^2+2xy+(iy)^2+(ix)^2 -2iixy=16i^2

by solving L.H.S.

we will get.,

4xy=-16

xy=-4

please rate me ,if i was right
