[umbral sundial]

you can factor out the numerator

and that will cancel out with the denominator

can you do this by yourself?

[sudden raft]

Easy af. Take any positive even number and place there instead of c. Ex.: You take c=10 => outcome: (6000+300) / (300+15)= 20

[wispy moss]

for 16 or 15

[sudden raft]

Use calculator XD

It doesn't matter

[wispy moss]

okay

[sudden raft]

15 -> 252/42=6

[sudden raft]

So you need one example with even and one with not*

[wispy moss]

okay so like 9

[sudden raft]

Ye

3 easier

[wispy moss]

alright btw were u get the 252 on 15

[sudden raft]

Yes

Idk what btw means

[wispy moss]

by the way

[sudden raft]

Calculator my friend xD

[fallow jay]

That's not the way. This doesn't prove that it will always ve an integer.

[sudden raft]

Wut

[fallow jay]

Factor out 2c from the numerator.

[fallow jay]

You need to show that it's an integer for any integer c, not just for some values.

[sudden raft]

Yes

[sudden raft]

But my explanation was ok?

[wispy moss]

guys how do i find the average spee for 584336233.6

[fallow jay]

No, it doesn't prove anything.

[sudden raft]

Write under postscriptum: not rational number

[fallow jay]

Not sure what you mean.

[sudden raft]

Condition

[umbral sundial]

doesnt prove it

[fallow jay]

Again, not sure what you mean. c is a positive integer.

[umbral sundial]

you do not show that there cant be any weird positive integer such that after substitution gives you an odd number

[sudden raft]

You can write in maths lang: " guys this thing works only with good integers bc I don't have time to talk you about odd ones"

[umbral sundial]

lmao

but really all you gotta do is factor the numerator and cancel out 3c^2 + 15

after this you're left with 2c, which is always even

[sudden raft]

This

[wispy moss]

i confusse now i do i just factoriese the c

[umbral sundial]

can you factorize the numerator

[wispy moss]

what does factorise mean

[umbral sundial]

break something down to factors

for example 66 can be factorized as 2 * 3 * 11

because 2 * 3 * 11 = 66

[wispy moss]

do i factorise the 15 or the 3c

[umbral sundial]

factor out the 2c from numerator

[wispy moss]

so it wouldd be 6c as numoretor and 3 as ddenominator

[umbral sundial]

no it would be

$\frac{6c^3+30c}{3c^2+15} = \frac{2c(3c^2+15)}{3c^2+15}$

[wispy moss]

oh

[umbral sundial]

because 30c = 15 * 2c and 6c^3 = 3c^2 * 2c

and then you see

we have a common factor 3c^2 + 15 in both numerator and denominator

can we cancel it out?

[wispy moss]

ye

[umbral sundial]

so after cancelling out we have 2c

which is always even because it is guaranteed to have a factor of 2

[sudden raft]

Damn you don't leave him time to think himself

[wispy moss]

so answer is 2c

[umbral sundial]

oops

[umbral sundial]

well it is asking us to show that this is always even

so the answer is something like

"we can cancel out common factor 3c^2 + 15 to show that the above expression is equal 2c. 2c is always even because it is guranteed to have a factor of 2"

[wispy moss]

oj okay

[hearty oak]

even times even = even

even times odd = even

[umbral sundial]

i, as a manager

hereby declare

gilf123 guy

actually nvm

your answer is reasonable
