Hello, I am just starting to learn limit evaluation techniques. I am unsure of the method used in this case.(adsbygoogle = window.adsbygoogle || []).push({});

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

limit tending towards infinity.

I know the first step is 'x^3 / x^4', then '1/x = 0'

But I dont understand how this came about.

Can someone please clarify these steps.

Thanks kindly if possible.
