What exactly do you mean by saying that the imaginary roots (usually
called complex roots by mathematicians) do not exist? What attribute
does -2 + i possess, or lack, that entitles you to attribute to it the
property of non-existence? How does -2 + i differ in that respect from
other numbers such as -1 or 42?
The fact is, there is a vast theory of complex analysis which is
coherent and fascinating. It is also useful in science and engineering.
