f(x)=2x^3-1/x^2(adsbygoogle = window.adsbygoogle || []).push({});

first I did this:

I used the quotient rule to get:

1.x^2(2x^3-1) + 2x^3-1(x^2)

2.x^2(6x^2) + 2x^3-1(x^2)

3.6x^4 + 4x+4 -2x

4.2x(3x^3+2x^3-1)/x^4

and I arrived with my final answer:

2x(3x^3+2x+3-1)/x^4

I know I got it wrong. But I would love to know why

and what I should have done instead. Thank you so

much for your help!
