My question asks me to write a solution in interval notation - if I have
(x-4)(x-3i)(x+3i)(x+4)0 is there a way to express the complex numbers in interval notation?

My question asks me to write a solution in interval notation - if I have 
(x-4)(x-3i)(x+3i)(x+4)>0 is there a way to express the complex numbers in interval notation?

Not really, I'm guessing you are not expected to consider the complex solutions.

not sure.. as I told you before it is diferent. You're no longer in |R, you're in |C with complex notation

that's right u would have to have two different sets of intervals and the meaning is completely different.

OK - thanks so much

Anyway, consider only the real numbers to do the interval.

x>4 or x< -4

the complex numbers are not an ordered field therefore < and > have no meaning
