# Math Help - Totaly easy limit :)

1. ## Totaly easy limit :)

How can you get 48 from this limit ? lim whn x goes to three of (6x^3-2x^2-5x) ?

2. You put x=3 in (6x^3-2x^2-5x)...

6*3^3-2*3^2-5*3=?

If you want the direct proof(with epsilon), you can ask...

Should the 6 be a 3 ?

I did it the same way, but the answer is not 48 as you can see ? So if this is the right way, then 48 is wrong ?
