Find dy / dx by implicit differentiation.
xy + 5x + 3x^2 = 5...
I got y'=(-y-5-6x)/x...but i got stuck

Question

amistre64 · Answer

[xy]' = x'y + xy'

[5x]' = 5

[3x^2]'=6x

[5]' = 0

amistre64 · Answer

x'y + xy' +5 + 6x = 0

y' = (-5-6x -y)/x

anonymous · Answer

yes...i got that steps i took all of the derviatives

amistre64 · Answer

where you stuck at?  you found the derivative

anonymous · Answer

sure looks good to me!

anonymous · Answer

that y'=(-5-6x-y)/x

anonymous · Answer

but how do i finish it?

amistre64 · Answer

by inserting whatever point they give you to fill in x and y

anonymous · Answer

you have a curve and have decided that y is a (implicit) function of x.  since you did not solve for y in terms of x your answer must have a y in it.  you are done

anonymous · Answer

haha there is no point i wish there was

amistre64 · Answer

then y' = what it equals and you are done with it

anonymous · Answer

o ok..so i had the answer right then

amistre64 · Answer

yes

ok thanks
