Quotient Rule, luv.

f'(x) = [(x^2) d/dx(2x^3 – 1) – (2x^3 – 1) d/dx(x^2)]/(x^2)^2

You should be able to get it from there.

Stupid poem to remember the Quotient Rule:

If the Quotient Rule you wish to know

It’s “low ‘d’ high less high ‘d’ low”

Then draw the line and down below

Denominator squared will go.

“Low” is the denominator. “High” is the numerator. “‘d'” is derivative.
