Answer 2

Okay, so, do you know what a conjugate is?

Answer 3

not really...I understand how to do 3i but I don't understand the rest

Answer 4

Okay, well, it almost means "opposite."
If you have x+2, the conjugate is x-2.
If you have 5 – 2i, the conjugate it 5 + 2i.

Answer 5

That obnoxious set of symbols is a minus sign :)

Answer 6

In these kinds of questions, the whole number will be the "real" part, and the number with the i in it will be the "imaginary" part of it

Answer 7

So if you have 2+3i, what is the conjugate?

Answer 8

Okay so it is 2-3i?

Answer 9

Yep! That's how you do conjugate :)

Answer 10

Thanks I get it now!! :)
