I also did that when I didn't get the answer same as mine but I think the difference is that X doesn't equal 0 and 4 in the same formation; X either equals 0 or 4 depends on what you solve for.. It doesn't equal 0 and 4 when we solve for the same variant such as
x (x-4)=0
Where X will...
My answers X=0 and Y=4 were correct, I talked to the teacher and he said the final answers given were wrong
Here's how I came up with it:
8i = 4xy + 2xi + 2yi + i^2 + 1
0 + 8i = 4xy + 2xi + 2yi -1 + 1 [ Since i^2 equals -1 ]
Real part = real part thus
0=4xy
X = 0/4y
X=0...
Homework Statement
8i = ( 2x + i ) (2y + i ) + 1
The final answers is [x =0, 4]
[y=4, 0]
