a: 5-8i b:5-2i c:-5+8i d:3i

- tkhunny

It would help if you wrote the original problem correctly.
It would also help if you showed YOUR work.

- anonymous

combine like terms
that is all

- SPHott51

4-2i -24i +12i^2
4 -26i -12 = -8 -26i ...?

- UsukiDoll

this is addition right? or is it multiplication? oh man I agree with tkhunny.

- anonymous

lol
at the risk of repeating myself, combine like terms \[-1+6x-4+2x\]

- UsukiDoll

I think...just a suggestion that if the original poster is typing the equations or questions wrong, we shouldn't go further unless there is more information.

- SPHott51

I fixed it.. happy now?

- UsukiDoll

much better.. now do what satellite said.

- SPHott51

This is an imaginary number...

- anonymous

then imagine that \(x\) is \(i\)
it is the same process

- SPHott51

isn't i^2 = -1 ?

- anonymous

yes, but there is no \(i^2\) in your question
think you might be confusing addition and multiplication

- UsukiDoll

true, but you're just adding and combining like terms for this one

- UsukiDoll

a typical problem for multiplication would look like this
(a+bi)(a-bi) but you don't have that

- SPHott51

oh........ thanks

- UsukiDoll

for this addition problem your final answer should look like one of these four
a+bi,a-bi,ai+b,ai-b

- UsukiDoll

the order doesn't matter that much

- SPHott51

yeah i got -5 +8i , it's one of the answer choices.

- UsukiDoll

that's correct
