@satellite73

Answer 5

your answer is going to be -6+3i

Answer 6

(−3 + 2i) • (2 + i)

Use FOIL:

= (-3)(2) + (-3)(i) + (2i)(2) + (2i)(i)

= -6 - 3i + 4i + 2i^2

= -6 + i + 2(-1)

= -6 + i - 2

= -8 + i

Answer 12

I think it's funny that @aurora007 already got two medals for her answer. Has anyone noticed it's wrong?

Answer 13

@HelpBlahBlahBlah where are you from

Answer 14

from the world of course

Answer 15

i know that much but i was wondering like what state or country are you from

Answer 16

Answer 17

Answer 18

mathstudent55 are you the one that said something stupid about Aurora007

Answer 19

I did write something about aurora's answer to the math question. I didn't write anything stupid about aurora.

Answer 20

next time dont write anything at all okay and your just( muy loco)

Answer 21

Ok, do you think it's better for the person who asked the question to have a wrong answer?

Answer 22

I just got home and my cousin was on my laptop and I didnt even answer the question she did and my abuela was suppose to be watching her but she still ended up with my laptop anyway

Answer 23

People ask math questions here to get help with their homework. How does a wrong answer help? It just confuses more the person who needs help.

Answer 24

i am a working person i told you already i just got home and i didnt anwser the question okay

Answer 25

If what you're saying is true, then you shouldn't let other people use your account and make you look bad.

Answer 26

Still, that's not the point. The point I was making is that you received two medals for giving out an incorrect answer. I think that is funny.

Answer 27

If I was at work how would i know if someone has been in my room on my stuff i wouldnt because i was gone all freaking day and your really pissing me off because i told you already that my cousin had my damn laptop and she answerd the question okay not me

Answer 28

I find it interesting that one moment your prima is using your computer at your casa and writes an incorrect answer, and just 4 minutes later, you are using the computer and explaining how your name came about. You sure drive fast from el trabajo to la casa. By the way, I think Aurora is a lovely name. It means Dawn.

Answer 29

it is also interesting how her first question was an hour ago, and yet she says she was gone all day.

Answer 30

Ok, Aurora, I'm not picking on you. We were just having some fun. Sorry if you got upset. I'll stop now. Have a great day.

Answer 31

Answer 45

I think we should all be nice to each other. Let's get back to math, and stop using the post area to call each other names. Aurora, it was nice meeting you online. If you ever need help with math, and I know the material, I'll try to help. You can tag me any time.
To @HelpBlahBlahBlah and @abracadabra , the same applies. Let's talk to each other nicely using messages, not the posts. If you have questions on math, tag me. I'll do my best to help.
