Question

which is the proper way to type my answer using parentheses? I have to type my answers as (a-bi)/c or (a+bi)/c. Thanks.

the answer is
4i-1
- ------
2
(with the minus sign before the fraction)
would I type -(1+4i)/2 or (1+4i)/2 or something totally different?

Thanks!!

Answer 1

-(4i-1)/2 is equivalent to \(\large\color{slate}{\displaystyle-\frac{4i-1}{2}}\)

if that is what you are asking

Answer 2

yes, but moving it to a-bi form... I lost points on my previous answers with format, so I want to make sure I get the format and the signs correct this time.

Answer 3

does the -( ) stay outside the () and it becomes -(-1+4i) or does it distribute and become (1-4i) ? Does that make sense?

Answer 4

for example:

-(ci-d)/2

(-ci+d)/2

(d-ci)/2

(d/2) - (c/2)i

Answer 5

do you want to know how to put the parenthesis and this is better, or should I post it in latex or draw it?

Answer 6

that is a+bi or a-bi form

Answer 7

It seems as though you are lost....

Answer 8

(with my explanation I wouldn't get surprised)

Answer 9

not really. I solved (3+5i)/(-2+2i), got -(4i-1)/2 answer, but lost points on format. Is there a "more correct" way to format the answer? Personally, I think either would be good, but my teacher seems to disagree. :)

Answer 10

you are entering the answer just using what your keyboard has to offer without attachments, pictures and such. This is why you have a problem, because you sometimes fail to correctly put the answer that you actually had in mind.

Is that right?

Answer 11

yes! only the keyboard :(

Answer 12

i have no way to attach it written for this problem, with my work. It's just the answer.

Answer 13

In my college email I use latex pictures if I want to communicate with my professor. (Any latex converter suffices. Then convert it to an image...)

but I guess we would HAVE TO comprehend the parenthesis spaces and everything

Answer 14

I might not be able to perfectly teach you right now, but you know what?

enter your input in here (all your parenthesis and etc.)

and wolfram is going to give you what you wrote an interpretation

Answer 16

This is an online HS course :) I prefer the assignments I can use Word equations or take a photo of my work for.

I'm betting it doesn't really matter the format :)

Thanks! I'll give it a try.

Answer 17

For example:
when I enter
(d/2) - (c/2)i

I will use wolfram to see what it would show.
http://www.wolframalpha.com/input/?i=%28d%2F2%29+-+%28c%2F2%29i

it just interpreted my input (under "Input")

Answer 18

it gave me 1/2 -2i ?

Answer 19

that means that -(4i-1)/2 is correct
