chrome wraith

hi so this is a hidden quadratic

chrome wraith Sep 7, 2024, 2:58 PM

#

hey

#

ok i see

primal loom Sep 7, 2024, 2:58 PM

#

ive got an answer but i think with this hint ur capable of doing it urself

chrome wraith Sep 7, 2024, 2:59 PM

#

dawg ion think so

primal loom Sep 7, 2024, 2:59 PM

#

is it +sqrt(1/4) and -sqrt(1/4)

chrome wraith Sep 7, 2024, 2:59 PM

#

one sec dude

primal loom Sep 7, 2024, 2:59 PM

#

so 1/2 and -1/2

chrome wraith Sep 7, 2024, 3:00 PM

#

how the hell

#

yes it’s right

primal loom Sep 7, 2024, 3:00 PM

#

ok imma send the working out

chrome wraith Sep 7, 2024, 3:00 PM

#

yk whats mad

#

i got all the working out right

#

just didn’t turn the x back into y correctly

#

i wanna kms now

chrome wraith

u good yh

chrome wraith Sep 7, 2024, 3:05 PM

#

yoooo

#

good for one of em

#

the logs one i’m stuck bro

muted lion Sep 7, 2024, 3:05 PM

#

Wat part

#

Getting it into the form?

#

Ok so

#

log a

#

u know a>0 always

#

Can’t take log of a negative

primal loom Sep 7, 2024, 3:06 PM

#

right dont mind the quality

muted lion Sep 7, 2024, 3:06 PM

#

so b>0

#

and the denominator can’t be 0

#

b>1

muted lion Sep 7, 2024, 3:06 PM

#

muted lion b>1

Try this @chrome wraith

muted lion Sep 7, 2024, 3:09 PM

#

primal loom

just times by y^4 straight away

primal loom Sep 7, 2024, 3:09 PM

#

yh could do that

chrome wraith Sep 7, 2024, 3:13 PM

#

my bad guys just got on the bus

#

@muted lion i’m tragic at logs full stop need to learnt the whole topic again

muted lion Sep 7, 2024, 3:13 PM

#

chrome wraith <@907751687782027334> i’m tragic at logs full stop need to learnt the whole topi...

u just need to know laws

chrome wraith Sep 7, 2024, 3:13 PM

#

yh and how to manipulate them ig

muted lion Sep 7, 2024, 3:13 PM

#

loga-logb=log(a/b)

chrome wraith Sep 7, 2024, 3:13 PM

#

yeah

muted lion Sep 7, 2024, 3:14 PM

#

brisk plume

Do u get this

#

Also is the answer b>1

chrome wraith Sep 7, 2024, 3:14 PM

#

muted lion Do u get this

it’s i get that

#

simple enough

#

primal loom so 1/2 and -1/2

HOW DO U KNOW THAT😭

#

tbf I would’ve probably done smth similar but

primal loom Sep 7, 2024, 4:08 PM

#

glacial herald HOW DO U KNOW THAT😭

magic

#

maths is just spotting patterns

#

hint in this case was the hidden quadratic

glacial herald Sep 7, 2024, 4:08 PM

#

That’s true tbf

#

Yh my first instinct was to make them have the same denominator

#

And then go from there

primal loom Sep 7, 2024, 4:09 PM

#

yep it's always helpful to do that

slow glen Sep 7, 2024, 5:42 PM

#

primal loom

interesting way

#

at the start

#

I think I would've just × everything by y⁴

#

so to get 3-10y²-8y⁴=0 instantly

primal loom Sep 7, 2024, 5:43 PM

#

yh i wrote more than i usually do

slow glen Sep 7, 2024, 5:43 PM

#

works tho

primal loom Sep 7, 2024, 5:43 PM

#

only downside is wasting time during the exam ig

#

if u even get qs like that

#

idk

slow glen Sep 7, 2024, 5:44 PM

#

eh

#

tbh I think you'd end up finishing a paper w time to spare
