Question

anonymous · Answer

they will be 2i and 4+i

anonymous · Answer

when dealing with imaginary numbers they come in congigate pairs

anonymous · Answer

oh ok i understand, but the -6 and 4 don't have conjugate pairs?

anonymous · Answer

no because they are real numbers so they dont need to be paired with their opposites

anonymous · Answer

basicaly what you are having is it will but some sort of square root of -1 so you will get a plus and minus i out of the deal thats why you have plus and minus 2i
ect.
