Domain Help

[jolly bronze]

I need help on a few problems for Algebra 1 of Domain... For now here is one of the problems

[obtuse sparrow]

What's the question?

[jolly bronze]

can u see the image above

[obtuse sparrow]

Yeah

[jolly bronze]

yeah thats the question

oh wait

I meant to say

I need to find Domain

[obtuse sparrow]

Oh, okay

[jolly bronze]

so how can I find it for that

[obtuse sparrow]

So, first simplify it

[jolly bronze]

ok done

my answer is 2x(x+y)

that shud be correct but it's saying no

[obtuse sparrow]

This has a domain of all real numbers

So you need to find the removable discontinuities, or holes as they're sometimes called

x /= y, x /= -y

Wait a second

Is this meant to be a function?

I'm so confused

[rain rover]

all the denominatoes cant be 0
the entire sum of fractions cant be 0 either

[jolly bronze]

I'll talkback to u later

[jolly bronze]

nah

[jolly bronze]

yeah ofc

but idk what equations shud I set equal to 0

[jolly bronze]

i think so

yea

[obtuse sparrow]

So is it 3 dimensional?

[rain rover]

I just said what equations should be set to 0...

all the denominators

and the (1/(y^2-x^2)+whatever)

[obtuse sparrow]

It's kinda weird though because there's only one side to the equation
