Help, I am infinitly confused :)(adsbygoogle = window.adsbygoogle || []).push({});

When solving the limit for this type and factoring the largest power of a variable in the polynomial in order to make its coefficient become a limit multiplied by another limit of Infinity I get lost. I just do not understand how (Infinity)(5 + Infinity + Infinity -Infinity) = (Infinity)(5). Where did all the other infinities go??

I hope that makes sense. There is much better examples on the first few problems on this page http://tutorial.math.lamar.edu/Classes/CalcI/LimitsAtInfinityI.aspx
