inequalities

[waxen rover]

x^2-(9/2)x=0

if you want to know how I did, here is what I did

I made the equation like this: (x-9/2)(x-0)=0

because the roots for the equation would be x=0 and x=9/2

so then simplifying it would be (x-9/2)(x)

They should be whole Numbers too so

[waxen rover]

oh yeah they are supposed to be integars

[serene vapor]

thank youuuu

do you guys happen to know any other servers like this?

like for biology

[waxen rover]

they should be integars

not whole numbers

[serene vapor]

or physics

[waxen rover]

i can invite u to a physics discord server

[serene vapor]

please do

[serene vapor]

question didnt specify?

or is that a rule for inequalities

[waxen rover]

they said write it in ax^2+bx+c form where a,b,c are integars

.solved

Solved

Use .unsolved if this was a mistake.

What’s the difference?

[waxen rover]

whole numbers are 0, 1, 2, 3, 4, 5,...

integars are ...-5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5,...

[frank tusk]

What you describe are natural numbers

[serene vapor]

ok ok help me with this one

@frank tusk @waxen rover

[frank tusk]

I can’t help. The way I’ve understood it Δ depends on x

[waxen rover]

natural numbers are {1, 2, 3, 4, 5,..}

[waxen rover]

i think u have to use b^2-4ac

so a=-1

b=2
c=-1

(2)^2-4(-1)(-1)

4-4(1)

4-4

0

so the discriminant is 0

@frank tuskwhat software do u use

[frank tusk]

I don’t see why you use the y value for the min/max point. Also I take a screenshot in my iPad and just draw over it

[serene vapor]

i fucking hate math

thanks tho

how do i close this forum

[vale falcon]

Bro

Do you not know the discriminant

[vale falcon]

Exactly

[waxen rover]

yes

if you are on pc/laptop right click on the forum channel and click unfollow post

if i did do ypu think i would have opened this forum
