tkhunny · Answer

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

anonymous · Answer

combine like terms 
that is all

sphott51 · Answer

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

usukidoll · Answer

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

anonymous · Answer

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

usukidoll · Answer

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 · Answer

I fixed it.. happy now?

usukidoll · Answer

much better.. now do what satellite said.

sphott51 · Answer

This is an imaginary number...

anonymous · Answer

then imagine that $x$ is $i$
it is the same process

sphott51 · Answer

isn't i^2 = -1 ?

anonymous · Answer

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

usukidoll · Answer

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

usukidoll · Answer

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

sphott51 · Answer

oh........ thanks

usukidoll · Answer

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

usukidoll · Answer

the order doesn't matter that much

sphott51 · Answer

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

usukidoll · Answer

that's correct
