Limiting x^2-x as x Approaches Infinity

[ggcheck]

lim (x^2 - x) as x---> inf.

I thought it was in indeterminate form inf. - inf. but my friend said that it's just inf.

please help

$$\lim_{x\rightarrow\infty}=x(x-1)$$

As x goes to infinity, infinity times infinity minus one goes to ... ?

Actually both of you are right. It is an "indeterminant form" but that doesn't mean it does not have a limit!
