Hey, I was wondering if there is a fast way to find the poles of a system - not using a calculator.(adsbygoogle = window.adsbygoogle || []).push({});

For example,

[tex]G(s) = \frac {30}{(s^2 + 6s + 20)(s + 2)(s + 13)}[/tex]

I know two poles right off the bat: -2 and -13, but is there a way to get the poles from the quadratic quickly? Besides the using the quadratic equation, I mean.

I don't think there is, but for some reason I thought I saw someone taking the "b" term, in this example 6s, and halving it. So the pole would be 3. I don't think this is right, is it?

Thanks.
