and simplify

Homework Equations

The Attempt at a Solution

as far as i could get was 8x(x²-3)³-18x²(2x³+1)²/(2x³+1)⁶

which is not simplified.

How can you simplify something like this? Is there a systematic way to approach it?

In general, what is the best method to approach really messy derivatives (such as this one, or any other that can be manipulated by algebra)?

Check your calculation: u=(x^{2}-3)^{4} and v=(2x^{3}+1)^{3}, then:
<br /> \frac{du}{dx}=8x(x^{2}-3)^{3}\quad\frac{dv}{dx}=18x^{2}(2x^{3}+1)^{2}<br />
From here the algebra is doable.
