8i = ( 2x + i ) (2y + i ) + 1
The final answers is [x =0, 4]
The Attempt at a Solution
The final answer in the book is stated as above but if I follow the solution I will get the real parts which would
Equal 0=4xy meaning that both x and y when solving for either wil equal zero. If I continue the result I will get is
[X= 0, Y= 4]
I get one solution instead of 2 as provided in the book..
