Best ResponseYou've already chosen the best response.03x^2+2xy+2x dy/dx +8x= 0 then isolate dy/dx and simplify from there. Do you get that or need me to explain it?

Best ResponseYou've already chosen the best response.0Ok so the first part 3x^2 is from the normal derivative way and then when we move on to derive x^2y we have to use the product rule : (x^2)(y) The product rule I hope you know already is (a'(x)*b)+(a*b'(x)) for ab respectively. Do you understand up to here?

Best ResponseYou've already chosen the best response.0How does the product rule look like when you derive \(\ x^2y?\)

Best ResponseYou've already chosen the best response.0It should be f'(x) *y + f(x) *y'. Derivative of x^2 is 2x and derivative of y is dy/dx.

Best ResponseYou've already chosen the best response.0What does the dy/dx mean? dy/dx of x^2? or y?

Best ResponseYou've already chosen the best response.0Let's say you had y^3 you would derive it as \[3y^2 \frac{ dy }{ dx }\]
