Are you saying that (infinity)^2 - (infinity) = infinity?
I know that the limit of x^2 as x tends to infinity is infinity. This led me to infinity minus infinity. How can it be that infinity minus infinity is infinity?

Apply Infinity Property:
lim ( ax^n+.....+bx+c ) as x->infinity =infinity , a>0, n is even

I didn't know that property either.
