Hello
Can someone tell me how to simplify this further?

(-18x^4)+(24^3)/(6x^3)^2

(6x^3)^2 is the common denom!

Please help

$-(18x^4) = -1 \times 6 \times 3 \times x^3 \times x$

$24x^3 = 4 \times 6 \times x^2 \times x$

Hi wolfhound,

Just to add a little to what $e^{i\pi}$ said....

$\frac{-18x^4+24x^3}{(6x^3)^2}=\frac{-6x^3(3x-4)}{(6x^3)(6x^3)}$

Can you take it from there?

4. Thank you e^(i*pi).

Yes this is the final answer I needed $\frac{-18x^4+24x^3}{(6x^3)^2}=\frac{-6x^3(3x-4)}{(6x^3)(6x^3)}$
Thanks

Surely $6x^3$ cancels?
