Question

Can you solve this? http://screencast.com/t/7IdaXwlofg

Answer 1

You'll need to use the product rule a few times
\[\huge \frac{ d }{ dx } \left[ x^2y+3xy^3 - x = 3 \right]\]

Answer 2

My result is dy/dx = (-2xy-3y^3+1)/(x^2+9xy^2) is it correct?

Answer 3

I uploaded a png file with the problem worked out

Answer 4

\[\huge 2xy + x^2 \frac{ dy }{dx } +3 y^3 + 9xy^2 \frac{ dy }{dx } -1 = 0\]

Answer 5

I got the same answer

Answer 6

Bravo!

Answer 7
