so if you don't know how to solve a question, try your best and fill in with your guess, then choose "grade now" and read through the solution

2021-03-07 03:19:39 UTC  

Lol

2021-03-07 03:20:07 UTC  

i'm trying to solve the integral question above <:SadPepe:801485397678489660> but i don't think i have learnt integrals during high school

2021-03-07 03:20:09 UTC  

Yeah I use that a lot. But my teacher is dumb and averages out every attempt. Instead of taking the highest one. Doesn’t make sense honestly

2021-03-07 03:20:24 UTC  

So basically I can do that, but it cost me points 

2021-03-07 03:21:43 UTC  

which one??

2021-03-07 03:21:44 UTC  

oh is it a quiz XD

2021-03-07 03:21:58 UTC  

Integrals are not fun

2021-03-07 03:22:05 UTC  

the given zeros are (-4, 4 + i) above

2021-03-07 03:22:22 UTC  

i found an example online but in the example both numbers are positive

2021-03-07 03:22:28 UTC  

yea

2021-03-07 03:22:55 UTC  

this is the example i found

2021-03-07 03:23:43 UTC  

i supposed in this case we can solve for half of the equations 🤔

2021-03-07 03:23:52 UTC  

4 +/- i

2021-03-07 03:24:15 UTC  

I think the answer is just (x^2)-16-xi-4i

2021-03-07 03:24:31 UTC  

but that just doesnt look right for some reason

2021-03-07 03:24:44 UTC  

maybe? this is the first time i run into integrals

2021-03-07 03:25:57 UTC  

I took a course on complex polynomials but that was a while ago

2021-03-07 03:27:24 UTC  

@isoboto I feel kinda dumb because I learned all this stuff but when anyone asks about it the first thing I do is google it.

2021-03-07 03:27:39 UTC  

shhhhh dont tell anyone

2021-03-07 03:28:54 UTC  

<:KEK:795742276549607456> that's me in every class

2021-03-07 03:29:11 UTC  

okay so i found another example

2021-03-07 03:29:25 UTC  

basically this is just expanding stuff? 🤨

2021-03-07 03:29:38 UTC  

not sure how the "i" works hmmmm

2021-03-07 03:29:41 UTC  

yea

2021-03-07 03:29:53 UTC  

oh then it should be easy (i think XD)

2021-03-07 03:29:58 UTC  

"i" is actually an unreal number

2021-03-07 03:30:11 UTC  

It is the square root of negative one

2021-03-07 03:30:25 UTC  

hmm okay so when expanding it, we keep it until the end?

2021-03-07 03:30:34 UTC  

so basically i^2 = -1

2021-03-07 03:30:35 UTC  

what puzzled me is the "+4" they had

2021-03-07 03:30:42 UTC  

ah, okay

2021-03-07 03:30:59 UTC  

in the question the person was asking, -4 was by itself

2021-03-07 03:31:06 UTC  

yea

2021-03-07 03:31:18 UTC  

the zeros were

2021-03-07 03:31:20 UTC  

-4

2021-03-07 03:31:22 UTC  

and

2021-03-07 03:31:29 UTC  

4 + i

2021-03-07 03:31:31 UTC  

yea
