...you use implicit differentiation.
Like, that's the "how".
Can you show your work?

dy/dx = -(3x^2+y)/(x+3y^2)
?
vestal flower
dy/dx = -(3x^2+y)/(x+3y^2)
?
...that's not your work.
That's one of the two solutions you say you got.

Can you show your work?
Looks like my difference to that answer is that my x is negative
those are prime symbols not to the power of 1

...that wasn't going to be my question.
My question was going to be where the negative came from.
terse cobalt
i suppose i kep the denominator the same from the prior step
i just merged the two fractions like i would when adding any other fractions with a common denominator
what would be the correct way to proceed from that step then?

What are we differentiating again?
terse cobalt
x^3 +xy +y^3 = 4?
vestal flower
So where's the negative?
terse cobalt
hm i think i've made a mistake in my earlier steps, let me redo this rq
I have the same answer now
Looks like I over complicated it last time
would this be correct now?

You still needing help with it?
