For x3y2+y3x=-6, find dy/dx. I get an answer that is close to the right answer, but either my y is off by an exponent or something.

What answer do you get ?

-3x2y2-y3 / 3x2y+y3

Okay but why didnt you make it like -3x2y2-y3 / 2x3y+3xy2

when numerator and denominator have common factor, we can simplify the quotient.
