Answer 1

\[\huge x ^{2}y +xy ^{2}=6\]
Find the derivative we have to use it again!!

Answer 2

Would we facttorise it ?

Answer 3

Find dy/dx

Answer 4

Try to factorise it and see what it gives us.

Answer 5

xy(x+y)

Answer 6

We shouldn't need to factor it
though that's a possibility
the first thing we'll want to do is to implicit differentiation
do you know what I mean by implicit differentiation?

Answer 7

Yes what we just did

Answer 8

ohhh yes in ur prev prob. :O
so can you find what the implicit derivative of this function will be?
