1. The problem statement, all variables and given/known data 8i = ( 2x + i ) (2y + i ) + 1 The final answers is [x =0, 4] [y=4, 0] 2. Relevant equations 3. 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..
