Homework Help: Math

Posted by Jack on Wednesday, October 5, 2011 at 6:59am.

I Don't Know What Is This Subject Called In English But It's About Complex Numbers
it says

25 = 16 - 9 i^2 = (4 3i)

But My Teacher Says

25 = 25 - 0 i^2 = (5 0i)

I Think My Teacher Is Wrong , The Result Is 25 But There Will Not Be Complex Number Because ( 0i = 0)
So Is My Teacher Wrong Or Not ?
