## FreeTrader 4 years ago Can this be simplified? (3x^3 + 1) / (x+1)

1. LagrangeSon678

according to the wolf, no

and Lagrange speaks wolf too !

This is a component of a Limit problem I have found to be DNE.

cool

Let me see what I started with...

ah, right, x --> -1, hence my passion to remove x+1 from the denominator.

This is a solve for limit that I have reached exhaustion upon. I think it is DNE. Lim (x--> -1) of (3x^3 + 1) / (x+1 I can find no result other than indeterminate, using a table shows the val's skate off to infinity in opposite directions as x approaches -1, which both my sketch and your wolf confirms on the chart. Am I missing something?

i think your are right

14. LagrangeSon678

The limit on the right does no equal the limit on the left

Right. Left != Right ----------> Lim DNE

Thanks for confirming my results - I am slowly building confidence in finding lim.

you get the above by doing polynomial division (well, wolf to save time and effort). http://www.wolframalpha.com/input/?i=%283x^3+%2B+1%29+%2F+%28x%2B1%29
