lim when x->-infinity

[Petrus]

Hello MHB,
I got stuck on this limit
\(\displaystyle \lim_{x->-\infty}x^2e^x\)

progress:
I did rewrite that as
\(\displaystyle \frac{e^x}{\frac{1}{x^2}}\) and then did variabel subsitution \(\displaystyle t=\frac{1}{x^2}\) but that did not work well,

Regards,

Try \(\displaystyle \frac{x^2}{e^{-x}}\)
